69.7

Answer: It has the meaning of establishing boundaries and divisions, because the internal, external, and intermediate are each established in opposition. The *Samuccaya* says: 'It has the meaning of the seed of all dharmas: that is, based on the seeds of all dharmas within the ālayavijñāna, they are designated as dhātu. Dhātu has the meaning of cause. Furthermore, it has the meaning of being able to uphold its own specific characteristics; it also has the meaning of being able to uphold the nature of cause and effect; and it also has the meaning of subsuming and upholding the differences of all dharmas.'
