And again why he lays down the Prânabhritah. From Pragâpati, when relaxed (by producing creatures), the vital airs departed. To them, having become deities, he spake, 'Come ye to me, return ye unto me that wherewith ye have gone out of me!'--'Well then, create thou that food which we will await here looking on!'--'Well then, let us both create!'--'So be it!'--So both the final airs and Pragâpati created that food, these Prânabhrit (bricks).
