Bhagavad Gita
14.17

सत्त्वात्सञ्जायते ज्ञानं रजसो लोभ एव च | प्रमादमोहौ तमसो भवतोऽज्ञानमेव च ||

sattvāt sañjāyate jñānaṁ rajaso lobha eva ca pramāda-mohau tamaso bhavato 'jñānam eva ca

Translation

From sattva springs knowledge; from rajas springs greed; from tamas spring negligence and delusion, and ignorance as well.

Interpretation

Each guna generates its characteristic inner experience. Sattva produces genuine knowledge — not merely intellectual information but the intuitive wisdom that sees clearly. Rajas produces greed — the insatiable appetite that can never be satisfied. Tamas produces negligence (failure to see what is important), delusion (mistaking the false for real), and ignorance (the absence of self-knowledge). Recognizing which inner state is predominant helps the practitioner identify which guna is active and choose appropriate responses to restore balance and cultivate sattva.
