Ancient Indian Alchemy extends as far as five thousand years and included metallurgy, āyurveda, siddhacikitsā, rasaśāstra (the "science of essential substances"), vājīkaraṇa, transmutational alchemy (dhātuvāda, the "doctrine of the elements"), elixir alchemy (dehavāda), hatha yoga and the most secret practices: Tantric Alchemy.

Tantric Alchemy practitioners believed that the universe constantly regenerates itself out of the sacred union of the divine through the mergence of masculine and feminine charged elixirs.

All vital animal, mineral, and plant-based substances are emanates of divine source of power. All aspects of creation participate in the same flow of Universal energy, thus all are considered by the Tantric Alchemist, interchangeable, recombinatory, and perfectible.

Many of the preparations and practices incorporating ancient alchemical practices in Tantra and Ayurveda were lost to time.

Elixirs & annointing preparations from these lost tantric practices were performed to extend life, heal incurable disease, restore power, improve cognitive function, and even reverse aging.

Many believed adept Tantric Alchemists prepared the Elixir of Immortality to achieve eternal life and ascend beyond our current dimensions.

The use of elixirs included similar preparations to Ancient Egyptian alchemical practices: distilled herbs, essential oils, crushed stones, sacred resins, flowers & spices.

These were blended into a mother elixir, chanted over, blessed, then sealed in jars and kept in dark cellars to mature.

Once considererd matured, small amounts of the "mother" would be blended into the masculine essences of honey or oils.

These blends would then be "potentiated" by being poured back and forth between two sacred vessals while chanted over to activate the prana and increase the vibrational life force of the elixir.

These potentiated elixirs could either be ingested or used to annoint oneself multiple times a day to achieve the desired results.
