SB 12.4.33
ghano yadarka-prabhavo vidiryate
caksuh svarupam ravim iksate tada
yada hy ahankara upadhir atmano
jijñasaya nasyati tarhy anusmaret
Translation:
When the cloud originally produced from the sun is torn apart, the eye can see the actual form of the sun. Similarly, when the spirit soul destroys his material covering of false ego by inquiring into the transcendental science, he regains his original spiritual awareness.
Purport:
Just as the sun can burn away the clouds that prevent one from seeing it, the Supreme Lord (and He alone) can remove the false ego that prevents one from seeing Him. There are some creatures, however, like owls, who are averse to seeing the sun. In the same way, those who are not interested in spiritual knowledge will never receive the privilege of seeing God.
