Yoga Nidra, also known as Sleep Yoga, is an ancient practice that allows one to relax while holding full awareness of the mind and body. It has benefits physically, emotionally, energetically, and spiritually. Swami Satyananda claims that many people don't know how to sleep. We often sleep while doing other activities such as reading, thinking, etc. When one finally falls asleep during this method, they don’t know when sleep actually comes and when consciousness begins to drift away. Thus, he/she falls asleep entangled in his/her thoughts, welcoming bad dreams. Sleeping in this manner does not allow one to be fully restful, having a negative effect on the mind and body. Stress usually stays on the mind during sleep as well. However, during Yoga Nidra, one does not only rest, but is able to reconstruct the ways of the mind and release pent up tension and stress, while keeping the mind present and aware. During this time, one can be brought into the Theta level of sleep, without completely surrendering to the fully sleeping level of Delta. When practicing Yoga Nidra, one can connect more with oneself while resting and rejuvenating, preparing for everyday life.
