Kirtan Kriya. A great Spiritual Cleanser. Kirtan Kriya is one of the most important meditations in Kundalini Yoga. The mind goes out of balance when the pineal gland is dormant. The imbalance makes it seem impossible to break mental and physical addictions. Whatever you need at the moment, it will readjust and align you to bring balance into your mind and thus your life. It is a catalyst for change because it is a very powerful spiritual cleanser.
