The term also appears in Asaṅga's classic Yogācāra work, the "Mahāyānasaṃgraha" (no Sanskrit original, trans. from Tibetan)":"These representations ("vijñapti") are mere representations ("vijñapti-mātra"), because there is no thing/object ("artha")...Just as in a dream there appear, even without a thing/object ("artha"), just in the mind alone, forms/images of all kinds of things/objects like visibles, sounds, smells, tastes, tangibles, houses, forests, land, and mountains, and yet there are no [such things/objects at all in that . "MSg II.6"The term is sometimes used as a synonym with "citta-mātra" (mere "citta"), which is also used as a name for the school that suggests Idealism. Schmithausen writes that the first appearance of this term is in the "Pratyupanna samadhi sutra", which states:This (or: whatever belongs to this) triple world (*"traidhātuka") is nothing but mind (or thought: *"cittamatra"). Why? Because however I imagine things, that is how they appear.</ref>
