YV 3.5l

By the fire the gods went to the world of heaven; they became yonder Krttikas; he for whom these are put down goes to the world of heaven, attains brilliance, and becomes a resplendent thing. He puts down the circular bricks; the circular bricks are these worlds; the citadels of the gods are these worlds; verily he enters the citadels of the gods; he is not ruined who has piled up the fire. He puts down the all-light (bricks); verily by them he makes these worlds full of light; verily also they support the breaths of the sacrificer; they are the deities of heaven; verily grasping them he goes to the world of heaven. He puts down the rain-winning (bricks); verily he wins the rain. If he were to put (them) down in one place, it would rain for one season; he puts down after carrying them round in order; therefore it rains all the seasons. 'Thou art the bringer of the east wind', he says; that is the form of rain; verily by its form he wins rain. With the Samyanis the gods went (sám ayus) to these worlds; that is why the Samyanis have their name; in that he puts down the Samyanis, just as one goes in the waters with a ship, so [1] the sacrificer with them goes to these worlds. The Samyanis are the ship of the fire; in that he puts down the Samyanis, verily he puts down a boat for the fire; moreover, when these have been put down, if the waters strive to drag away his fire, verily it remains unmoved. He puts down the Aditya bricks; it is the Adityas who repel from prosperity him who being fit for prosperity does not obtain prosperity; verily the Adityas [2] make him attain prosperity. It is yonder Aditya who takes away the brilliance of him who having piled up a fire does not display splendour; in that he puts down the Aditya bricks, yonder sun confers radiance upon him; just as yonder sun is radiant, so he is radiant among men. He puts down ghee bricks; the ghee is the home dear to Agni; verily he unites him with his dear home [3], and also with brilliance.
