This talk introduces the practice of ‘complete Yoga Nidra; the spaciousness of your being' by exploring the symbolism of ‘Om' and how the waking, dream and deep sleep states all appear within something vast and unfathomable. Understand the science that underpins the philosophy and how our brain produces unique signatures or brain waves, in each state. James also explains how Yoga Nidra takes us into an effortless state of 'alpha' brain waves, giving us access to the Turya state, the very depths of the true self.
