Four krosha, each of which was the length of / One thousand arcs, each of which was the length of / Four cubits, each of which was the length of / Two spans, each of which was the length of / Twelve phalanges of fingers, each of which was the length of / Seven grains of barley, each of which was the length of / Seven mustard seeds, each of which was the length of / Seven particles of dust stirred up by a cow, each of which was the length of / Seven specks of dust disturbed by a ram, each of which was the length of / Seven specks of dust stirred up by a hare, each of which was the length of / Seven specks of dust carried away by the wind, each of which was the length of / Seven tiny specks of dust, each of which was the length of / Seven minute specks of dust, each of which was the length of / Seven particles of the first atoms.
