Having quitted his hold (of Soma) he sits down by him, with, 'May all thy people descend to thee.' Now, in saying, 'Descend unto all thy people,' he does what is unseemly, for Soma being the nobility, he thereby, as it were, confounds good and bad,--and, indeed, in consequence thereof, people now confound good and bad. But in this (formula) he does what is right and according to order,--in saying, 'May all thy people descend to thee,' he makes all his subjects go down (on their knees) before him; and hence when a noble approaches, all these subjects, the people, go down before him, crouch down by him on the ground. Sitting near (Soma), the Hotri is about to recite the morning-prayer.
