I often mention that Yoga Nidra and NSDR are supported by modern science. Today, I’d like to share another perspective — the science of yoga itself and its traditional view, which I find endlessly fascinating. In Vedanta and yoga philosophy, human existence is described as five layers, known as koshas (or bodies): Annamaya kosha: the food body, is the physical body of blood, bone, fat, and skin, which is perceived through the senses Pranamaya kosha , the pranic body, is the underlying energy network of the human structure, which consists of currents of prana Manomaya kosha , the mental body, is the layer of conscious operation within the sphere of the mind Vijnanamaya kosha , the psychic body, is the dimension of our personality which is operating on the astral plane Anandamaya kosha , the bliss body, is the transcendental dimension of the human personality existing in total absence of pleasure or pain In Yoga Nidra, awareness doesn’t stop with the physical body. The practice gradually guides you through these layers: First, the body softens — muscles, sensations, tension releasing. Then, the breath and energy begin to balance. The mind follows, with thoughts and emotions settling. With practice, awareness can touch subtler layers of clarity, intuition, and eventually a quiet state beyond thought. This step-by-step journey is what makes Yoga Nidra feel so different from ordinary rest. It creates space for all your layers to release and deeply rest.
