Kundalini yoga as taught by Yogi Bhajan is a no nonsense, effective practice of postures, mantra and breathwork. It doesn't shy away from what is frustrating, uncomfortable or looks weird. Instead it embraces all that and works through it, evolves it. This is the power of kundalini yoga, it gives you an experience. An experience of your own consciousness. There is nothing outside of you. Simultaneously scary and liberating.
Come and try for yourself.
