So far it is established that it would be a great folly to identify 'I' with the body.

What about mind? Is 'I' the mind? Because mind seems to be controlling all the senses. If mind is absent senses do not work. For example, while listening to anything if mind wanders here and there, words are not heard even after entering the physical ears. It means that 'I' does not need body to function and hence 'I' is not the body but it could be mind. Mind can perform all the functions of all the senses without assistance from physical senses as it happens in dreams.

All the actions originate in mind and therefore mind is the sole doer of actions. Thus there are firm indications that 'I' is mind. However it cannot be true.

Consider the deep sleep. During the deep sleep, mind does not function. Yet the bliss, called deep sleep is experienced by someone. On getting up, we say 'Oh! I had an excellent sleep. I did not see even dreams!' Which means 'I' is present even if mind is absent. Therefore 'I' cannot be mind.

What about intellect? Intellect is not different from mind altogether. It is one of the states of mind in which decisions are taken. Hence when mind does not work, intellect too is at rest.

Thus 'I' is not the physical body, it not the mind nor intellect! Thus by elimination rule one one conclusion prevails..'I' is different from Body, mind and intellect and that it must be soul.
