 The individual soul is the bearer of its body, its vehicle (Mulla Sadra 2001–5, IX: 63–4). It comes into existence with the body and still retains the sense of being the entelechy of the body which is why the two cannot be detached (Mulla Sadra 2004: 240). Just as existence is not an accident of essence but is the principle to which an essence is attached, similarly the soul is not an accident of the body (Mulla Sadra 1981: 139). He cannot admit the pre-existence of particular human souls because that might open the way towards metempsychosis which is a doctrine that he vehemently rejects in his eschatology.
