Vritti-Nirodhah and Thought-Pattern Interruption

Patanjali defines yoga as 'chitta vritti nirodhah'—the cessation of mental modifications or thought patterns. This is not merely philosophical abstraction but a practical intervention into the thought-somatic feedback loop that perpetuates vagal dysregulation. When the nervous system detects threat (real or imagined), it generates loops of anxious thinking; these thoughts then reinforce the sympathetic or dorsal vagal state through bottom-up processing. By cultivating the capacity to interrupt mental fluctuations—through concentration, meditation, or deliberate mental redirection—practitioners break this cycle at the psychological level. This creates space for the vagus nerve to recalibrate. Vritti-nirodhah offers a psychological lever for what polyvagal theory addresses somatically: when the mind becomes still, the nervous system naturally gravitates toward ventral vagal safety, social engagement, and clarity. The practice validates that mental discipline is nervous system regulation.
