Pranayama — The Science of Breath and the Veil Over Consciousness
Pranayama (the regulation of the life-force through breath) removes the veil that covers the Inner Light — Patanjali's most precise description of how breath practice directly affects consciousness.
Sutras 2.49-2.53 describe Pranayama as the fourth limb of Ashtanga Yoga. Pranayama is the regulation of the incoming (puraka), outgoing (rechaka), and retained (kumbhaka) movements of breath, with attention to the place where breath operates, its duration, and its count. The key is sutra 2.52: 'tatah kshiyate prakasha avaranam' — from pranayama the veil covering the Inner Light is destroyed. This sutra makes a remarkable claim: pranayama directly dissolves the veil of Avidya that obscures the light of pure consciousness. Not metaphorically but literally: the regulation of prana (life-force, which breath is the gateway to) directly affects the state of chitta in ways that the regulation of thought alone cannot. Sutra 1.34 offers the simplest form: the controlled exhalation and retention of breath (pracchardana vidharana) steadies the mind.
From pranayama, the veil covering the Inner Light is destroyed.
Neuroscientist Stephen Porges' Polyvagal Theory documents how slow, regulated breathing activates the ventral vagal system, producing states of calm alertness — exactly the 'uncovered inner light' Patanjali describes — while dysregulated breathing activates defensive arousal states that obscure this clarity.

- What the Yoga Sutras say about breath and pranayama
Here is the claim itself: from breath regulation, the covering over the inner light thins. Patanjali does not say breathing relaxes you, he says it removes something standing between you and clear seeing.
