New Delhi, October 4, 2017 : You might have been moved by the way followers of the Hindu dharma bow down and welcome you inside their homes. Or by the way Hindu women dress, with jewellery adorning their hands and legs. Who doesn’t like the crinkling of their bangles, after all? But have you ever wondered the rationale behind their customs and traditions?

According to popular notions, the traditions and practices of the Hindu dharma have been equated with superstitions. However, a deeper look into the practices reveal that they are based on scientific knowledge and have been observed over generations , keeping in mind a more holistic approach.

Hinduism can hence, be called a dharmic scientific religion rather than just scientific religion. We prove you how!

 1. Worshiping the Peepal tree

Hindu dharma entails a myriad gods and goddesses and there exist a variety of reasons that propagate worship of Peepal tree. According to Brahma Purana, demons Ashvattha and Peepala hid inside and lured people to touch the Peepal tree and consecutively killed them. They were killed by lord Shani and hence the tree has been worshiped ever since. Another legend believed Goddess Lakshmi resides under the Peepal tree every Saturday which lends it a divinely touch. Another school of thought believes lord Hanuman sat on top of the Peepal tree in Lanka to witness the hardships faced by Sita.

The Peepal tree does not have a succulent fruit, lacks strong wood and does no good other than provide shade. However, it continues to enjoy increasing devotion from people practicing the Hindu dharma. Science confirms that Peepal is the only tree which produces oxygen even during the night. Hence, in order to preserve this unique property, ancestors of the Hindu dharma related it to God. Additionally, the tree is of utmost significance in Ayurveda and its bark and leaves are used to treat diseases and illnesses.

 2. Do not chew leaves of Tulsi plant

The Tulsi plant is revered in the Hindu dharma. Apart from its medicinal qualities, the plant is also known for its symbolic presence in Hindu mythology.

According to popular belief, Tulsi is the wife of Lord Vishnu. Hence, biting and chewing it is considered disrespectful.

However, according to botanists, Tulsi has high quantities of mercury. If raw mercury comes in contact with teeth (calcium), it can possibly result in inundation, making the teeth fall. Hence, leaves of the Tulsi plant are suggested to be swallowed and not chewed.

 3. Applying tilak on your forehead

Application of tilak is a religious ac. According to the Hindu dharma, the forehead signifies spirituality. Hence, application of a tilak on the forehead denotes an individual’s thoughts and conviction towards spirituality.  Various Vedic scriptures and Upanishads maintain that energy, potency and divinity comes to those who apply a tilak.

However, science asserts that during the application of a tilak, the central point in the forehead and the Adnya-chakra automatically pressed which encourages blood supply to the facial muscles.  According to body anatomy, a major nerve point is located in the middle of the eye brows on the forehead. Application of the red tilak is believed to maintain vitality in the body and prevent the loss of energy. The Tilak is also believed to control and enhance concentration.

 4. Obsessive cleaning during Diwali

Diwali, the festival of lights honors the goddess Lakshmi, the deity of wealth. The festival also commemorates the return of lord Ram after an exile of 14 years to his kingdom in Ayodhya. According to Hindu mythology, the night of his return was a new moon night. To illuminate his path in the pitch dark night, the villagers of Ayodhya cleaned the entire village and lit it with lamps.

Hence, Diwali is preceded by extensive cleaning of the entire house in honor of both the deities of Hindu mythology. Legend also believed goddess Lakshmi comes home on Diwali and thereby, the entire place should be cleaned and decorated to welcome the goddess.

However, science backs the concept and explains that Diwali essentially falls in October and November, and mark beginning of winters and end of monsoon season.

In older times, the monsoons were not a good period as they were characteristic of excessive rains that often resulted in floods and damaged homes, which then needed repair. This is why people indulged in repair, cleaning and beautification of their homes.

 5. Folding your hands for ‘Namaskar’

You will often find people practicing Hindu dharma greeting people by joining their palms together. The ‘Namaskar’ is believed to signify respect for people.

This pose requires an individual to join all finger tips together that carry the pressure points of ears, eyes and mind. Science says pressing them together activates these pressure points, making our mind attentive.  This aids us to remember people for a longer duration.

The Namaskar can also be backed up by an act to maintain hygiene and cleanliness since it does not involve any physical contact.

 6. Wearing toe rings

Traditionally, toe rings are worn by married woman on the second toe and are treated as a sign of holy matrimony. However, they are believed to be a part of the Indian culture since the times of Ramayana when Sita threw her toe ring for her husband lord Ram, upon being abducted by Ravana.

Science says that a nerve on this toe connect the uterus to the heart.  Wearing a ring on this finger helps regulate blood flow, thereby, strengthening the uterus and regulating menstrual cycle. It is also believed to have an erotic effect.

 7. Applying henna on hands and feet

Mehendi or henna is usually applied during weddings and festivals to enhance the beauty of the women-folk. According to popular beliefs, the color of the henna denotes the affection a girl will enjoy from her husband and mother-in-law.

However, science provides rationale of applying henna during the stressful times of festivals and weddings. Festivity stress can bring fevers and migraines, which when mixed with excitement and nervous anticipation can prove to be harmful for an individual.

Thus, besides lending color, henna also possesses medicinal qualities that relieve stress and keeps the hands and feet cool thereby shielding the nerves from getting tense.

 8. Fasting during Navratri

There are four major Navratris throughout the year, however only two are celebrated on a grand scale. Throughout the nine day festival, devotees observe ritualistic fasts, perform several pujas and offer bhog (holy food) to Goddess Durga in an attempt to gratify her.

But according to science, these navratris are celebrated when the seasons are transitioning. As the seasons and the temperatures change, our eating habits also do.

Fasting during Navratri allows our bodies to adjust to the changing temperature. Individuals get a chance to detox their bodies by quitting excessive salt, sugar and oil. Additionally, Navratris allow them to meditate and gain positive energy. This helps them prepare for the upcoming change in seasons.

 9. Applying sindoor

In traditional Hindu societies, the Sindoor denotes a woman’s desire for their spouse’s longetivity. The red powder is believed to be the color of power, symbolizing the female energy of Parvati and Sati. The Hindu dharma holds a woman is ‘complete’ or ideal only when she wears Sindoor.

Science explains that sindoor is made out of Vermilion, which is the decontaminated and powdered type of cinnabar (mercury sulfide). Because of its characteristic properties, mercury is known to reduce anxiety, control blood pressure and also initiate sexual desire, the primary reason why married women are advised to wear the ‘holy’ red powder. This is also the reason why widows are prohibited from wearing sindoor.

10. Wearing bangles on wrists

Bangles have been worn in the Hindu dharma since times immemorial- goddesses are also pictured to adorn these beautiful rings in their wrists. Bangles are believed to enhance feminine grace and beauty. The Hindu dharma almost makes it mandatory for newly-wed brides and to-be brides to wear bangles as they are believed to symbolize the well-being of the husbands and the sons.

Science suggests the constant friction caused by wearing bangles in the wrists expands the blood flow level. Besides this, the energy passing through the external skin is once again returned to one’s own body due to the round-molded bangles which has no ends to pass the energy out.

Invasive Species May Not Be All Bad: Scientists

An active debate among biologists about the role of invasive species in a changing world is going on

Invasive Species

Off the shores of Newfoundland, Canada, an ecosystem is unraveling at the hands (or pincers) of an invasive crab.

Some 1,500 kilometers (930 miles) to the south, the same invasive crab — the European green crab — is helping New England marshes rebuild.

Both cases are featured in a new study that shows how the impacts of these alien invaders are not always straightforward.

Around the world, invasive species are a major threat to many coastal ecosystems and the benefits they provide, from food to clean water. Attitudes among scientists are evolving, however, as more research demonstrates that they occasionally carry a hidden upside.

“It’s complicated,” said Christina Simkanin, a biologist at the Smithsonian Environmental Research Center, “which isn’t a super-satisfying answer if you want a direct, should we keep it or should we not? But it’s the reality.”

Simkanin co-authored a new study showing that on the whole, coastal ecosystems store more carbon when they are overrun by invasive species.

Good news, crab news

Take the contradictory case of the European green crab. These invaders were first spotted in Newfoundland in 2007. Since then, they have devastated eelgrass habitats, digging up native vegetation as they burrow for shelter or dig for prey. Eelgrass is down 50 percent in places the crabs have moved into. Some sites have suffered total collapse.

That’s been devastating for fish that spend their juvenile days among the seagrass. Where the invasive crabs have moved in, the total weight of fish is down tenfold.

The loss of eelgrass also means these underwater meadows soak up less planet-warming carbon dioxide from the atmosphere.

In Cape Cod, Massachusetts, the same crab is having the opposite impact.

Off the coast of New England, fishermen have caught too many striped bass and blue crabs. These species used to keep native crab populations in check. Without predators to hold them back, native crabs are devouring the marshes.

But the invasive European green crab pushes native crabs out of their burrows. Under pressure from the invader, native crabs are eating less marsh grass. Marshes are recovering, and their carbon storage capacity is growing with them.

Carbon repositories

Simkanin and colleagues compiled these studies and more than 100 others to see whether the net impact on carbon storage has been positive or negative.

They found that the ones overtaken by invasive species held about 40 percent more carbon than intact habitats.

They were taken by surprise, she said, because “non-native species are thought of as being negative so often. And they do have detrimental impacts. But in this case, they seem to be storing carbon quicker.”

At the Smithsonian Environmental Research Center where she works, the invasive reed Phragmites has been steadily overtaking a marsh scientists are studying.

Phragmites grows much taller, denser and with deeper roots than the native marsh grass it overruns.

But those same traits that make it a powerful invader also mean it stores more carbon than native species.

“Phragmites has been referred to as a Jekyll and Hyde species,” she said.

Not all invaded ecosystems stored more carbon. Invaded seagrass habitats generally lost carbon, and mangroves were basically unchanged. But on balance, gains from marsh invaders outweighed the others.

Not a lot of generalities

To be clear, Simkanin said the study is not suggesting it’s always better to let the invaders take over; but, it reflects an active debate among biologists about the role of invasive species in a changing world.

“One of the difficult things in the field of invasion biology is, there aren’t a lot of generalities,” said Brown University conservation biologist Dov Sax, who was not involved with the research. “There’s a lot of nuance.”

The prevailing view among biologists is that non-native species should be presumed to be destructive unless proven otherwise.

When 19 biologists wrote an article in 2011 challenging that view, titled, “Don’t judge species on their origins,” it drew a forceful rebuke from 141 other experts.

Sax said the argument is likely to become more complicated in the future.

“In a changing world, with a rapidly changing climate, we do expect there to be lots of cases where natives will no longer be as successful in a region. And some of the non-natives might actually step in and play some of those ecosystem services roles that we might want,” he said.

“In that context, what do we do? I definitely don’t have all the answers.” (VOA)
