A further passage in the 8,000 line Prajñāpāramitā sutra states that Prajñāpāramitā means that a Bodhisattva stands in emptiness (shunyata) by not standing ("√sthā") or supporting themselves on any dharma (phenomena), whether conditioned or unconditioned. The dharmas that a Bodhisattva does "not stand" on include standard listings such as: the five aggregates, the sense fields (ayatana), nirvana, Buddhahood, etc. This is explained by stating that Bodhisattvas "wander without a home" ("aniketacārī"); "home" or "abode" meaning signs ("nimitta", meaning a subjective mental impression) of sensory objects and the afflictions that arise dependent on them. This includes the absence, the "not taking up" ("aparigṛhīta") of even "correct" mental signs and perceptions such as "form is not self", "I practice Prajñāpāramitā", etc. To be freed of all constructions and signs, to be signless ("animitta") is to be empty of them and this is to stand in Prajñāpāramitā. The Prajñāpāramitā sutras state that all Buddhas and Bodhisattvas in the past have practiced Prajñāpāramitā. Prajñāpāramitā is also associated with "Sarvajñata" (all-knowledge) in the Prajñāpāramitā sutras, a quality of the mind of a Buddha which knows the nature of all dharmas.
