Yoga Nidra is the systematic method which aims at a deep relaxation of the human body, while maintaining its awareness. For this reason, etymologically Yoga (join-consciousness) Nidra (sleep) means “conscious sleep”. Through this technique, the body is led to a state between sleep and awareness, in which it is possible to approach the mind’s subconscious and unconscious side in order to allow a controlled release of its contents. More specifically, through Yoga Nidra, we can manage the tension that accumulates in the body and relates to all its functions, the mind and the recordings that accumulate daily, while at an emotional level, the tension caused by oppressed emotions and anxiety. Basically, this method can be a first step in the practice of meditation, as the practitioner lies in deep relaxation trying to maintain an increased ability of perception.
