Yoga Nidra, often translated as "yogic sleep," is a systematic, guided meditation practice designed to induce a state of complete physical, mental, and emotional relaxation. Unlike traditional meditation, which is typically performed in a seated, upright position, Yoga Nidra is practiced lying down in Savasana (corpse pose), making it accessible to nearly everyone regardless of physical ability.

The goal of the practice is to enter a hypnagogic state, the liminal space between wakefulness and sleeping. While the body rests deeply, the mind remains awake and alert. Through a specific series of verbal cues, usually provided by an instructor or a recording, the practitioner is guided through a rotation of consciousness. This involves moving awareness to different parts of the body, engaging in breath awareness, and utilizing visualizations to unlock deep layers of the subconscious.

A key component of Yoga Nidra is the Sankalpa, or heartfelt intention. At the beginning and end of the session, practitioners mentally repeat a positive affirmation or resolve. Because the mind is in a highly receptive, relaxed state (often associated with Theta and Delta brainwaves), the Sankalpa is believed to take root more effectively, helping to reshape negative thought patterns and habits.

The benefits of Yoga Nidra are profound. It is highly restorative; 45 minutes of Yoga Nidra is often said to feel as rejuvenating as three hours of regular sleep. It is widely used to reduce stress, alleviate anxiety, manage chronic pain, and regulate the nervous system by shifting the body from "fight or flight" into the "rest and digest" parasympathetic mode.
