Sūtra translation
From thence (the souls are led) by him only who belongs to the lightning ; the sacred text stating that.
From thence, i. e. after they have come to the lightning they go to the world of Brahman, being led through the worlds of Varu;/a and the rest by the person, not a man, who follows immediately after the lightning. For that that person leads them is stated in the following passage, ‘ When they have reached the place of lightning a person, not a man, leads them to the world of Brahman’ (Br/. Up. VI, 2, 15). Varuwa and the rest, we must understand, favour them either by not hindering or somehow assisting them. — Therefore it is well said that light and so on are the gods who act as conductors.
