Hṛdayānanda: (translating question:) There are many religions that speak of the light. How can we know we are actually facing the real light?
Prabhupāda: Light is to be realized personally. Light... Just like this room is dark. When there is light, it doesn't require to be enquired, "Is it light?" You personally perceive it is light. Just like you are hungry and foodstuff is given to you and when your hunger is satisfied, appetite is appeased, then you naturally you feel, "Yes, I am satisfied." You don't require to enquire anyone. Therefore it is called self-realization. Automatically you realize. You don't require to enquire. This is the process.
