Kundalini Yoga is not designed to challenge you physically, so in that regard, it isn’t considered a difficult practice. However, this does not mean that Kundalini Yoga will be a walk in the park for everyone that practices it. This practice is designed to unleash inner energy through a Kundalini awakening, which can be a very spiritually and emotionally challenging experience. If you’re not ready to experience this change, or you are resistant to these concepts, then you may find Kundalini Yoga to be very difficult and unpleasant. The best way to prepare yourself for this practice is to find a knowledgeable and qualified teacher who can gradually and safely guide you towards a Kundalini awakening.
