Yoga Nidra derives its name from the Hindu mystical Goddess Nidra, the deity associated with sleep and spiritual awakening. Goddess Nidra holds a prominent position in Hindu mythology as a divine being connected to spiritual rejuvenation and laya (slumber). She is revered as a celestial force endowed with the power to bestow restful slumber and revitalize vitality. Ancient sacred texts and epics attest to the enduring presence and influence of Goddess Nidra. Her blessings bring peaceful rest, renewed energy, and a connection to consciousness that leads toward self-realization.

This sacred practice of deep rest serves as a gateway to entering the void—a space of rest, release, and remembrance. It is within this space that the practice of Pratyahara, the fifth limb of yoga as outlined in the eightfold path described by the sage Patanjali in the Yoga Sutras, is embodied. Pratyahara involves turning inward by withdrawing attention from external distractions and sensory stimuli. It acts as a bridge between the external limbs (focused on ethical living and physical practices) and the internal limbs (focused on meditation and self-realization) of yoga. As a foundation for deeper concentration (Dharana), meditation (Dhyana), and ultimately spiritual enlightenment (Samadhi), Pratyahara is a cornerstone of the Yoga Nidra practice.
