摩訶止觀 5.91

5.91

As for the inconceivable realm: as the Avataṃsaka Sūtra states: 'The mind is like a skilled painter, creating the various five aggregates; in all worlds, there is nothing that is not created from the mind.' The 'various five aggregates' are like the five aggregates of the ten dharmadhātus mentioned before. 'Dharmadhātu' has three meanings: the number ten is the supported, and dharmadhātu is that which supports; combining supported and supporter in name, it is therefore called 'ten dharmadhātus'. Furthermore, these ten dharmas each have their own causes and each have their own effects, without becoming mixed or confused; therefore, they are called 'ten dharmadhātus'. Furthermore, these ten dharmas in their very essence are each the dharmadhātu; therefore, they are called 'ten dharmadhātus' [and so forth].
