Gurudāsa: Isn't brahma-jyotir temporary in the fact that you can come back down to the earth? Back to the material world?
Prabhupāda: Brahmacārī?
Gurudāsa: Brahmajyoti.
Prabhupāda: No. Brahmajyoti means spiritual sky. This material sky means brahma-jyotir is covered by material cloud. Actually, everything is brahma-jyotir. Just like clear sky, but some portion of the sky is sometimes covered by cloud. Some portion only. The whole sky is never covered by sky. Similarly, some portion which is covered by this material atmosphere, that is called material world. That's all. Actually, the original sky is spiritual. Original sky is full of sunshine, but the covered portion means we cannot see the sunshine. Covered portion by cloud means we cannot see the sunshine. And similarly, this material sky means where we cannot see the spiritual effulgence. That is the difference. Otherwise, even this material sky is also a spiritual sky. The spiritual sky is the original status. Yes.
