Then he eats with the following Rik verse at every foot: 'We choose that food'—here he swallows—'Of the divine Savitri (prâna)'—here he swallows—'The best and all-supporting food'— here he swallows — "We meditate on the speed of Bhaga (Savitri, prâna)'—here he drinks all.

In plain words: He eats the mash in small swallows, one after each line of a sacred verse. The verse praises the food of the sun god Savitri, here meaning the life-breath, as the best food that supports everything. At the last line he drinks all that is left.
