13.63

述曰：異熟生有二種：一、從異熟種子生，二、從異熟相續生。第六識中是異熟種子生，名假異熟，如眼根非真異熟，其第八識是異熟相續生，前念後念皆異熟故，今前念後念皆是異熟者能執持，非六種識，故有異也。即以此文，一師云：欲界有第六識異熟心，一師云：此乃遮計。又彼外計汝宗第七識應得，執持身何勞第八者，應立量云：我第七識不能執持身，非異熟性故，如六種轉識等。

The commentary states: There are two kinds of 'arisen from maturation': first, arising from the seeds of maturation; second, arising from the continuum of maturation. Within the sixth consciousness, it arises from the seeds of maturation and is called provisional maturation, just as the eye-faculty is not true maturation. The eighth consciousness arises from the continuum of maturation, because both the prior moment and the posterior moment are maturation. Now, that in which both the prior moment and the posterior moment are maturation can sustain [the body], not the six consciousnesses; hence there is a difference. Relying precisely on this text, one master says: 'In the desire realm, there is a retributive mind of the sixth consciousness'; another master says: 'This is merely to reject that posited view.' Furthermore, that outsider posits: 'In your school, the seventh consciousness should be able to sustain the body; what need is there to labor with the eighth?' One should formulate the syllogism: 'My seventh consciousness cannot sustain the body, because it is not of the nature of maturation, like the six evolving consciousnesses, etc.'
