Guṇa-vibhāga: The Three Modes and the Path Beyond Them
पुरुषं सत्त्वसंयुक्तमनुमीयाच्छमादिभि: । कामादिभी रजोयुक्तं क्रोधाद्यैस्तमसा युतम् ॥ ९ ॥
puruṣaṁ sattva-saṁyuktam anumīyāc chamādibhiḥ kāmādibhī rajo-yuktaṁ krodhādyais tamasā yutam
One who displays qualities such as self-control is understood to be predominated by sattva (goodness). One marked by lust and the like is in rajas (passion), and one marked by anger and the like is in tamas (ignorance).
This verse says goodness is known by qualities like calmness and self-control, passion by lust and restless desire, and ignorance by anger and related dark tendencies.
In the Uddhava Gītā, Kṛṣṇa trains Uddhava in discernment so he can diagnose material conditioning and cultivate the qualities that support bhakti and transcendence.
Observe your dominant emotions: choose practices that increase calm discipline (sattva), reduce lust-driven distraction (rajas), and avoid anger-fueled reactions (tamas) through mindful restraint and devotional focus.
