俱舍論疏 12.155

12.155

論「勿復麁色生無種子故」，勝論答。彼執劫壞壞餘麁色，祖極微散在虛空中，然在空中各各別住。劫將成時，兩兩和合生一子微，量等父、母。又微和合共生一孫極微，等二子微，如是乃至展轉成器世間，根本以最極細祖微為種。若此祖微亦令盡者，後子等微生即無種。

The treatise says: "Lest coarse form arise again without a seed." The Vaiśeṣikas answer. They maintain that when the kalpa is destroyed, it destroys the other, coarse forms, while the original atoms are scattered in empty space, but abide separately and individually within space. When the kalpa is about to form, they combine two by two to produce one binary atom, equivalent in size to its 'father and mother'. Furthermore, the binary atoms combine to jointly produce one tertiary atom, equivalent to two binary atoms; proceeding in this way from one to the next, the receptacle world is formed, having as its seed the most subtle, original atoms as root. If these original atoms were also exhausted, the subsequent binary and further atoms would arise without a seed.
