The ancient texts claim that as humans age, the "nectar" produced in the brain drips downward and is "burnt" by the digestive fire in the stomach (metabolism), leading to decay. Kayakalpa practices—specifically Kriya Yoga and Pranayama —aim to reverse this flow. By conserving this vital fluid and redirecting it back up the spine (via the Sushumna nadi), the practitioner aims to stop the "leakage" of life force, effectively hitting "pause" on the biological clock. kayakalpa
