Viññāṇa is consciousness arising in dependence on a sense and its object: eye-consciousness, ear-consciousness and so on, with mind-consciousness as the sixth. It is the fifth aggregate and, in dependent origination, conditions name-and-form. Yogācāra later developed the analysis into eight kinds of consciousness.
