Now, those same (priests) having, while gliding along, deposited that glory in him who sits through (celebrates) the praise of Agni, they glide along and turn away from that glory: having thus encompassed it, he again takes that glory unto himself;-- verily, whosoever, knowing this, sits through (celebrates) the praise of Agni, he passes away after becoming the most glorious of these (men).
