Chapter VII · Śloka 28
Śrī Kṛṣṇa uvāca
येषां त्वन्तगतं पापं जनानां पुण्यकर्मणाम् ।
ते द्वन्द्वमोहनिर्मुक्ता भजन्ते मां दृढव्रताः ॥
yeṣāṃ tv anta-gataṃ pāpaṃ janānāṃ puṇya-karmaṇām |
te dvandva-moha-nirmuktā bhajante māṃ dṛḍha-vratāḥ ||
But those persons of virtuous deeds, whose sin has come to an end, freed from the delusion of the pairs of opposites, worship Me with firm resolve.
Liberation from dvandva-moha is the fruit of long purification through puṇya-karma (virtuous action). When the karmic residue of sin is exhausted (anta-gataṃ pāpaṃ), the mind becomes clear enough to see through the pairs of opposites and takes refuge in the divine with dṛḍha-vrata — unshakeable commitment.
