13. Next the Saman addressed to the Visve Devas: 'Open the door of the world (heaven), let us see thee, that we may rule supreme (in heaven).'

14. Then he sacrifices, saying: 'Adoration to the Adityas and to the Visve Devas, who dwell in heaven, who dwell in the world. Obtain that world for me, the sacrificer!'

15. 'That is the world for the sacrificer! I (the sacrificer) shall go thither, when this life is over. Take this! Cast back the bolt!' Having said this, he rises.

16. For him the Adityas and the Visve Devas fulfil the third oblation. He who knows this, knows the full measure of the sacrifice, yea, he knows it.

Footnotes

^36:1 The commentator is always very anxious to explain that though it is better that a priest should know the hidden meaning of the sacrificial acts which he has to perform, yet there is nothing to prevent a priest, who has not yet arrived at this stage of knowledge, from performing his duties.
