瑜伽師地論略纂 1.15

1.15

意地三義：一、六根中意；二、六識中意；三、第七意攝。如次配之。然六識亦得名身。此第二釋。猶如心受唯名為意，不與身名者，自體依聚，識可名身；所依非色，故名心受。初後二解略故，不說身相應言，由此不說心、識二地。

The mental bhūmi (manobhūmi) has three meanings: first, the manas among the six sense faculties; second, the manovijñāna among the six consciousnesses; third, subsumption by the seventh manas. They correspond in this order. However, the six consciousnesses may also be called kāya. This is the second explanation. Just as mental feeling is called solely "mental" and not given the name of kāya, because consciousness is an aggregate of supports of its own essence, it can be called kāya; but since its basis is non-physical, it is called mental feeling. The first and last two explanations are concise, and thus do not use the words "associated with the collection", and for this reason they do not speak of bhūmis of mind (citta) or consciousness (vijñāna).
