Surrender is a function of the 7th chakra, located at the crown of the head. Here, above all thought and emotion, there can be a direct communion with the Universal. Yogi Bhajan gave this "Meditation of Ecstasy" to help us drop the self-conscious mind and immerse ourselves in the Infinite, clearing away the urge to become.
Sit in a cross-legged meditation posture with hands in Gyan Mudra and eyes closed. Inhale deeply and chant the mantra "Wa-hay Guru, Wa-hay Guru, Wa-hay Wa-hay, Wa-hay Guru" on one breath.
Chant in a monotone for 11 minutes. Then inhale deeply and hold the breath while concentrating the energy at the top of your head. After 30 seconds exhale and relax.
Wa-hay Guru expresses ecstasy and wonder at the perfection of this. Listen to the sounds you are making and let them connect you with a divine sound within. Practicing this meditation for 40 consecutive days is particularly powerful.
