In the spiritual effulgence, if we do not have any rest, then we are sure to come back again down. The reason is - that I have already explained - that our life... We, as living entities, we are part and parcel of the Supreme, sac-cid-ananda. We want pleasure. So impersonal feature does not give us that pleasure which we want, which is our demand. That pleasure is available in the spiritual planets. If you enter in any of the spiritual planets, then that spiritual happiness and exchange of pleasure you can attain.
