Nidra as a Mental Modification (Varkritti) (Abhava-Pratyayalambana Vritti)
Sleep is not merely the absence of thought; it is an active vritti resting on the experience of non-being that can be consciously witnessed.
Sleep is not merely the absence of thought; it is an active vritti resting on the experience of non-being that can be consciously witnessed. In the classical text Yoga Sutras 1.10, this principle is expounded as a vital cornerstone of energetic and physical mastery. When practiced with dedication, the seeker harmonizes their internal biological rhythm with the broader cosmological currents. Modern empirical observations confirm that deliberate synchronization of these cycles transforms cognitive acuity, emotional resilience, and cellular longevity.
Sleep is not merely the absence of thought; it is an active vritti resting on the experience of non-being that can be consciously witnessed.
This principle bridges classical esoteric physiology with modern autonomic neuroscience, demonstrating how breathing mechanics directly steer brainwave activity, metabolic rate, and psychological states.
