'Agni's coupling-link thou art,'--this fire-altar is the year, and it is joined together by means of the seasonal (bricks): he thus makes the year continuous, and joins it together by means of the seasons;--'May Heaven and earth fit into one another! may the waters and plants fit into each other!'--he thereby makes everything here to fit in by means of the seasons:--'May the fires fit into one another, each singly, working harmoniously together for my supremacy!'--for these single bricks are the same as those fires: he thus says this so that they may fit in with each other for the supremacy of those two seasons:--'whatever fires there are, at one with each other, within these two, Heaven and Earth;'--as the text is, so is its meaning;--'let them draw together, fitting in with the two dewy seasons, even as the gods draw together unto Indra;'--that is, 'even as the gods are drawing together round Indra, so may they draw together for supremacy round these two seasons.' Two bricks there are, because the season consists of two months. Only once he 'settles' them: he thereby makes the season to be one.
