Answer: The simultaneous base takes only the active manifestation of the six sense-bases and does not take seeds, because [seeds] lack the characteristic of possessing an object. If one merely speaks of the six faculties, this extends to both seeds and active manifestations. Furthermore, 'simultaneous base' takes the meaning of that which is relied upon, whereas if one speaks of the 'six faculties,' it takes the meaning of generating and growing; each is discussed according to its prominence. Moreover, when citta and caitta phenomena arise and abide, they possess simultaneous bases. When material phenomena arise and abide, having only the causal condition base is sufficient; they definitely lack a simultaneous base, because material phenomena have no cognitive objects and their own substance is not a phenomenon that can cognize. Furthermore, the Yogācārabhūmiśāstra states: 'For the five consciousnesses there are three bases: first, the seed-base; second, the simultaneous base; third, the opening-and-guiding base.'
