Next, after giving to all living beings the fruits of their work, the sun will be above such obligations. It will no longer rise nor set and will stay by itself midway. Here is a verse on the subject:
(In answer to a question)—No, indeed, in Brahmaloka the sun never rose, nor did it ever set. O gods, (listen and bear witness to me). What I am saying is true, and by it may I have no hindrance to my realization of Brahman.
For him who knows the secret teachings of Brahman there is no sunrise or sunset (or day or night). For him there is always day (i.e., light).
First, Brahmā taught this instruction on honey to Prajāpati. Then Prajāpati taught it to Manu, and Manu taught it to his children. The father Aruṇa then taught this knowledge of Brahman to his eldest son Uddālaka Āruṇi.
This knowledge of Brahman a father will pass on to his eldest son or to a competent resident student.
This should never be taught to anyone else, even if one is tempted with the whole world full of riches and surrounded by water. For this knowledge is more precious than that. This knowledge is surely more precious than that.
