Bhagavad Gita · Chapter 5: Renunciation in Action

Bhagavad Gita 5.16

jñānena tu tadajñānaṃ yeṣāṃ nāśitamātmanaḥ | teṣāmādityavajjñānaṃ prakāśayati tatparam ||

But for those whose ignorance of the self has been destroyed by knowledge, that knowledge, like the sun, lights up the Supreme.

Modern context

When ignorance is removed, knowledge shines like the sun. The image is exact. The sun does not create the landscape. It shows what was there all through the night. Understanding likewise makes nothing new. It reveals what was always the case. And as the sun needs no second light to be seen by, real understanding carries its own certainty. When something has truly been understood, one does not need someone else to confirm it.
