The Self is a multitude. In John there are many Johns. In Jane there are many Janes. Therefore, John might meet some problems in coming to terms with himself. Equally, Jane might have various difficulties in understanding herself. So, we should all avoid to think about ourselves in terms of a uniform oneness. In fact, it is true that there is an undisputable connectedness between each part of the universe (that is our theory of considering the cosmos as a whole). Nonetheless, it is also true that we are a composition of different instances. In fact, in our daily, ordinary experience, we know that there is in ourselves a spiritual part as well as a pragmatist part. We have logic as well as irrationality. We have CONCRETENESS as well as imagination.
The Self is a multitude. Into each one of us do live a legion of disparate instances and entities. In such a situation one must be blind and deaf (in front of this complex inner reality) in order to feel lonely. A fruitful inner dialogue is always possible between the soul, the ego, the mind, the conscience, the psyche, the unconscious, etcetera. Moreover, the soul itself is not a oneness, the ego itself is not a oneness, and so on.
