The document describes the Maha Vedha Mudra technique. It involves holding the breath and throat lock while placing the palms on the ground. This causes the prana energy to leave the ida and pingala nadis and enter the central sushumna nadi. Regular practice of this technique can provide great perfections and benefits like avoiding wrinkles, grey hair, and tremors of old age. It also helps catch and redirect sexual energy upward through closing the perineum. The technique involves concentrating prana in the cavity where the five nadis unite, which is the source of knowledge.
