Practicing the art of Yoga on a regular basis helps to eradicate a sense of individual separateness and lack. The comprehensive art of Yoga is not just limited to physical asanas, it also includes breathing techniques, which increase the circulation of prana or life force energy, in addition to meditation and contemplative practices that help to ease anxiety, depression and an abiding sense a separateness.
