• Regions of brain (e.g. brainstem) are highly evolved in survival; control such complex functions such as respiration w/ speed/precision that is far beyond comprehension by conscious mind
• Instinctive power is stored in these regions of brain
• Hatha Yogic breathing techniques "yoke" or connect the conscious mind to primal instinctive regions of brainstem
• Athletes & martial arts practitioners access breath's primal force by timing moments of exertion w/ forced exhale - Yogis refine this by coordinating the rythm of breath w/ movements in Asanas, generally coupling inhalation w/ expansion & exhalation w/ deepening
• Pranayama perfects this process
