Yogi Bhajan recommends starting low and working your way up to eleven minutes on each side, which would result in a 22-minute practice.
The primary purpose of the Kundalini Kriya is for converting semen into Ojas, which is described as extracting lifeforce from semen and bringing it back into the body. It's essentially a sublimation practice for transmitting sexual energy to the higher chakras.
This video introduces a Kundalini Yoga Kriya from Yogi Bhajan designed to convert sexual energy (semen) into Ojas, a vital life force. The practice involves a specific sequence of movements on all fours, alternating arm and leg lifts with breath holds and pumping actions, aiming to sublimate sexual energy to higher chakras. It's presented as beneficial for both men and women, particularly for those beginning to control their sexual energy or feeling energetic build-up.
The practice involves lifting the right arm, bending it at the elbow, and making a fist while keeping the arm held up. Simultaneously, the left leg is lifted behind. Then, with a deep inhalation and holding the breath, the leg is pumped up and down eight times, acting like a lever for the swadhisthana chakra to push energy upwards. After pumping, the breath is exhaled, and the sequence is repeated. The sides are then switched.
