Bhagavad Gita Chapter 7, Verse 28

येषां त्वन्तगतं पापं जनानां पुण्यकर्मणाम् | ते द्वन्द्वमोहनिर्मुक्ता भजन्ते मां दृढव्रताः ||

yeṣāṁ tv antagataṁ pāpaṁ janānāṁ puṇya-karmaṇām te dvandva-moha-nirmuktā bhajante māṁ dṛḍha-vratāḥ

But those who are free from the delusion of duality, whose sins have been destroyed by virtuous actions, they worship Me with firm resolve.

Krishna describes those who overcome delusion. 'Yeṣāṁ tv antagataṁ pāpaṁ janānāṁ puṇya-karmaṇām'—of those whose sins have been destroyed by virtuous actions. 'Te dvandva-moha-nirmuktā bhajante māṁ dṛḍha-vratāḥ'—they, free from the delusion of duality, worship Me with firm resolve. This verse shows how to overcome delusion: through virtuous actions that destroy sin, freeing one from the delusion of duality. Those who are free worship Krishna with firm resolve. This connects to verse 7.27's teaching about delusion from duality and provides the solution.
