Kaya Kalpa is an invaluable asset handed down to humankind by the saints of yore. It had for some reason remained forgotten or hidden from mankind through the centuries, but has fortunately now come to light once again. A wrong notion that Kaya Kalpa is a form of tonic or medicine persists in the minds of many. This is not correct. Kaya Kalpa is not a medicine; it is a practice which tones up the nerves, improves health and assures longevity in life. It is an art, perfected by the Siddha saints for the benefit of posterity.
