nominal existent (prajñapti) referring to the mere destruction (khayamatta) of the defilements or non-existence of the five aggregates, as was held by some in the Sautrantika school for example. In Theravāda scholasticism, nibbana is defined as the cessation (nirodha) consisting in non-arising and exists separately from the mere destruction of passion, hatred and delusion. Theravāda exegetical works, mental phenomena last for a very short moment or instant (khaṇa), but physical phenomena do not. Theravāda holds that the Buddha resided in the human realm (manussa-loka). It rejects the docetic view found in Mahayana, which says that the Buddha's physical body was a mere manifestation, emanation or magical creation (nirmāṇa) of a transcendental being, and thus, that his birth and death a mere show and unreal. Also, the Theravāda school rejects the view that there are currently numerous Buddhas in all directions. Theravāda holds that there is a ground level of consciousness called the bhavaṅga, which conditions the rebirth consciousness. Theravāda rejects the Pudgalavada doctrine of the pudgala ("person" or "personal entity") as being more than a conceptual designation imputed on the five aggregates. Theravāda rejects the view of the Lokottaravada schools which held that the all acts done by the Buddha (including all speech, defecation and urination, etc.) were supramundane or transcendental (lokuttara). Also, for Theravāda, a Buddha does not have the power to stop something that has arisen from ceasing, they cannot stop a being from getting old, sick or dying, and they cannot create a permanent thing (like a flower that doesn't die). Theravāda traditionally defends the idea that the Buddha himself taught the Abhidhamma Pitaka. This is now being questioned by some modern Theravādins in light of modern Buddhist studies scholarship. Theravāda, nibbana is the only unconstructed phenomenon (asankhata-dhamma, asankhatadhatu). Unlike in the Sarvāstivāda school, space (akasa), is seen as a constructed dhamma in Theravāda. Even the four noble truths are not unconstructed phenomena, neither is the domain of cessation (nirodhasamapatti). "Thatness" (tathatā) is also a constructed phenomenon. According to the Dhammasangani, nibbana, the unconstructed element, is 'without condition' (appaccaya) and is different from the five aggregates which are 'with condition' (sappaccaya). In Theravāda, the bodhisatta path is suitable only for a few exceptional people (like Sakyamuni and Metteya). Theravāda also defines a bodhisatta as someone who has made a vow in front of a living Buddha. In Theravāda, there is a physical sensory organ (indriya) that conditions
