《瑜伽》八十六云：由三解脫門增上力故，立四嗢拕南。一切行無常，一切行苦者，依無願立；一切法無我者，依空建立；涅槃寂靜者，依無相立。准此所明，無願攝十二，無常通三諦故，空攝十六，皆無我故。無相攝四，滅是涅槃故。依通行相，先無所願，次方觀空，因空證滅，第六復次。依七十二，三解脫與五事相攝中，若是相邊十六行相，各通三攝。彼云如是，五事幾是空、是空境，無願、無相為問亦同。

Fascicle eighty-six of the Yogācāra says: "Due to the predominant power of the three doors to liberation, the four udānas are established: 'All conditioned phenomena are impermanent' and 'All conditioned phenomena are suffering' are established based on the wishless; 'All phenomena are without self' is established based on emptiness; 'Nirvāṇa is peaceful' is established based on the signless." According to what is explained here, the wishless subsumes twelve, because impermanence extends to three truths; emptiness subsumes sixteen, because all are without self; and the signless subsumes four, because cessation is nirvāṇa. In accordance with the common aspects: first there is nothing wished for; next one contemplates emptiness; and by means of emptiness one realizes cessation; this is the sixth alternative. According to [fascicle] seventy-two, in the mutual subsumption between the three liberations and the five factors, if it is from the side of the marks, the sixteen aspects are each commonly subsumed by the three. It says there: "In this way, among the five factors, how many are emptiness, or the object of emptiness?" The questions for the wishless and the signless are also the same.
