An explanation of the Buddhist doctrine of karma (action) is central to Yogācāra, and the school sought to explain important questions such as how moral actions can have effects on individuals long after that action was done, that is, how karmic causality works across temporal distances. Previous Abhidharma Buddhist schools like the Sautrantika had developed theories of karma based on the notion of "seeds" ("bījā") in the mind stream, which are unseen karmic habits (good and bad) which remain until they meet with the necessary conditions to manifest. Yogācāra adopts and expanded this theory. Yogācāra then posited the "storehouse consciousness" (Sanskrit: "ālayavijñāna"), also known as the basal, or eighth consciousness, as the container of the seeds. It simultaneously acts as a storage place for karmic latencies and as a fertile matrix of predispositions that bring karma to a state of fruition. In the Yogācāra system, all experience without exception is said to result from karma or mental intention ("cetana"), either arising from one's own subliminal seeds or from other minds.
