THE NECTAR OF IMMORTAL LIFE

There is a potion that when ingested, is believed to grant eternal life; it's the elixir of life, or nectar of immortal life. This elixir of life is known by many different names through many cultures; names such as, ambrosia, amrita, liquid gold, soma, haoma, etc. What is exactly this potion or elixir of life?
In the sacred Indian text of the Rig Veda, written by the seer Rishi Kashyapa, there is an entire chapter devoted to a mysterious substance called soma, also called Soma Pavamana or Indu, which promises eternal life. Soma is a drink of living drops that come from the stalks of a legendary soma plant.

Here are a few verses of the Rig Veda;
"Where light is perpetual, in the world in which the sun is placed, in that immortal imperishable world place me, Pavamana; flow, Indu, for Indra. Where in the third heaven, in the third sphere, the sun wanders at will, where the regions are filled with light, there make me immortal; flow, Indu, for Indra. Where there is happiness, pleasures. joy and enjoyment, where the wishes of the wisher are obtained, there make me immortal; flow, Indu, for Indra."

Many believe that soma is a compound found in a rare Himalayan plant called knotweed vine, which might be the potent antioxidant resveratrol proven to slow down the aging process.
The yogis believe that soma can be self-generated in the pineal gland, thus, rejuvenating the body. But, there is a special way to obtain the soma, and it's only through deep meditation practiced for long periods of time, as well as through a special Yogic exercise called khechari mudra, combined with the meditation.
Therefore, you must first delve into meditation practice with a pure intent and perseverance. 

Khechari mudra:
The word khechari means to roll back your tongue and focus on the point between your eyebrows, either with closed or open eyes. The purpose of this mudra is to raise the kundalini and access the immortal elixir produced in the pineal gland. According to the Vedas, this elixir brings health, spiritual awakening and immortality.
To practice it, roll your tongue upward and backward, so the lower surface of your tongue comes into contact with your upper palate. Stretch the tip of your tongue backward as far as possible, without straining and keep the pressure at that point. At the same time, focus your attention on the third eye center, between your eyebrows, with your eyes open or closed. You can also do rhythmic breathing exercises when doing the khechari mudra.
