Summary
Krishna explains the three modes of material nature: Sattva (goodness), Rajas (passion), and Tamas (ignorance).
Verse 26
मां च योऽव्यभिचारेण भक्तियोगेन सेवते । स गुणान्समतीत्यैतान्ब्रह्मभूयाय कल्पते ॥
māṃ ca yo ’vyabhicāreṇa bhakti-yogena sevate | sa guṇān samatītyaitān brahma-bhūyāya kalpate ||
One who engages in full devotional service, unfailing in all circumstances, at once transcends the modes of material nature and thus comes to the level of Brahman.
