SB 1.3 - The same potency acting in two ways

If the illusory energy subsides and the living being becomes fully enriched with knowledge by the grace of the Lord, then he becomes enlightened with self realization and becomes situated in his own glory. The wise understand that such a person is worthy of worship. The Lord reveals Himself unto that person whom He alone chooses. If māyā withdraws her influence, then the Lord favors the devotee. Or when māyā withdraws her influence, the jīva thinks of the Lord. The transcendental energy of the Lord acts according to His omnipotency. The same energy acts as His external, internal and marginal energies, and He can perform anything and everything thru these energies. He can turn the external energy into internal by His will. Thus by His grace the external energy, which is employed in illusioning the living beings, subsides by the will of the Lord in terms of repentance and penance for the conditioned soul. And the very same energy then acts to help the purified soul make progress on the path of self realization.

The external energy which bewilders the living being is turned into internal potency by the will of the Lord to lead the living being to eternal life. The Lord’s external energy which facilitates our illusion can also carry us closer to Kṛṣṇa. Parīkṣit instructs us how to respond to the external energy, so that it will bring us closer to Kṛṣṇa. When the sage’s son cursed Parīkṣit to die in seven days, the king accepted it, for he ever remained receptive to Kṛṣṇa’s desire. When one responds properly, the external energy acts as internal energy. When Duryodhana insulted Vidura, Vidura perceived Kṛṣṇa’s mercy thru the insults.
