SB 1.3.34

yady eṣoparatā devī
 māyā vaiśāradī matiḥ
sampanna eveti vidur
 mahimni sve mahīyate
Word for word: 
yadi — if, however; eṣā — they; uparatā — subsided; devī māyā — illusory energy; vaiśāradī — full of knowledge; matiḥ — enlightenment; sampannaḥ — enriched with; eva — certainly; iti — thus; viduḥ — being cognizant of; mahimni — in the glories; sve — of the self; mahīyate — being situated in.
Translation: 
If the illusory energy subsides and the living entity becomes fully enriched with knowledge by the grace of the Lord, then he becomes at once enlightened with self-realization and thus becomes situated in his own glory.
Purport: 

Because the Lord is the Absolute Transcendence, all of His forms, names, pastimes, attributes, associates and energies are identical with Him. His transcendental energy acts according to His omnipotency. The same energy acts as His external, internal and marginal energies, and by His omnipotency He can perform anything and everything through the agency of any of the above energies. He can turn the external energy into internal by His will. Therefore by His grace the external energy, which is employed in illusioning those living beings who want to have it, 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 living being make progress on the path of self-realization. The example of electrical energy is very appropriate in this connection. The expert electrician can utilize the electrical energy for both heating and cooling by adjustment only. Similarly, the external energy, which now bewilders the living being into continuation of birth and death, is turned into internal potency by the will of the Lord to lead the living being to eternal life. When a living being is thus graced by the Lord, he is placed in his proper constitutional position to enjoy eternal spiritual life.
