Vritti: Mental Modifications and Internal Parts

Patanjali identifies five vritti—correct knowledge, misperception, imagination, sleep, and memory—which form the foundation of mental activity. In Internal Family Systems, each internal part generates its own vritti, or characteristic thought patterns and perceptions. A protective part may generate vritti of fear and vigilance, while an exiled part creates vritti of shame or despair. By recognizing these modifications as natural mental phenomena rather than absolute truth, we gain distance from reactive parts. The Yoga Sutras teach that liberation comes through witnessing vritti without identification. Applied to IFS, this means observing each part's mental modifications with curiosity and compassion, distinguishing between the part's protective strategy and the Self's witnessing awareness. This practice transforms our relationship with internal conflict from identification to conscious observation.
