Rasayana
The science of rejuvenation in Ayurveda, literally meaning 'the Path of Rasa', focused on purifying and nourishing Rasa Dhatu to produce healthy Shukra and Ojas.
Rasayana: The Path of Rasa
The word used in Ayurveda for both rejuvenation and rejuvenating substances is rasayana, which literally means the Path of Rasa. To walk the Path of Rasa you must purify and nourish your physical Rasa Dhatu, since Rasa is the raw material from which the other dhatus are formed.
Healthy Rasa Dhatu is the first step in the physical production of healthy Shukra, from which Ojas is directly produced. Careful selection of food tastes (Rasas) and control of emotions (Rasas) ensures production of healthy Rasa Dhatu, which can then generate healthy Shukra and Ojas.
Because Shukra is best nourished by Sweet, rejuvenation requires the creation of powerful Sweetness in body and mind.

Longevity and the Slow Life
Rejuvenation is the first step in the direction of immortality. Old age is an autoimmune disease — an admission by ahamkara that she is no longer adequately able to identify with the body.
Old age is caused by repeated indulgence in sensory pleasures, whose wear and tear on the body destroys Ojas. The faster you live, the faster you will deteriorate. Hummingbirds flit just a few seasons, but tortoises plod along for decades and centuries.
Longevity requires slowness, for a slow life permits your protective aura to interpose itself more efficiently between you and the outside world.
