CAUTION - Kundalini Yoga is a powerful science and I would like to pass on the warnings from Kundalini Yoga teachers I have studied under to approach your practice with intelligence and respect. If you are practicing at home, please remember not to do excessive chakra meditations. Too much flow of energy (shakti) before your body is ready to handle is extremely dangerous Please don’t forget to use common sense and do your practice in moderation. Always allow your body to rest after practice and don’t forget to drink plenty of water.
