Vritti: Mental Modification Patterns

Vritti, or mental modifications, are the thought patterns that color our perception and belief formation. Patanjali identifies five primary vritties: correct knowledge, misperception, imagination, sleep, and memory. These mental patterns act as filters through which we interpret experience and construct beliefs about ourselves and the world. When we misidentify a rope as a snake in dim light, we're experiencing vritti in action—our beliefs about danger form instantly from incomplete information. Understanding these modification patterns reveals how beliefs emerge not from objective reality but from the mind's habitual ways of processing experience. By observing which vritti dominates our thinking, we gain leverage to interrupt automatic belief formation and choose more accurate interpretations of life events.
