Yogācāra gives a detailed explanation of the workings of the mind and the way it constructs the reality we experience. According to Lusthaus, "the most famous innovation of the Yogācāra school was the doctrine of eight consciousnesses." These "eight bodies of consciousnesses" ("aṣṭa vijñānakāyāḥ") are: the five sense-consciousnesses, "citta" (mentality), "manas" (self-consciousness), and the storehouse or substratum consciousness (Skt: "ālayavijñāna"). Traditional Buddhist descriptions of consciousness taught just the first six "vijñānas", each corresponding to a sense base ("ayatana") and having their own sense objects. Standard Buddhist doctrine held that these eighteen ""dhatus"" or components of experience, "exhaust the full extent of everything in the universe, or more accurately, the sensorium." These six consciousnesses are also not substantial entities, but a series of events, arising and vanishing, stretching back from beginningless ("anadi") time.
