Whenever I have used the term "the centre of his being," I have referred to a state of meditation, to an experience which is felt at a certain stage. The very art of meditation is a drawing inwards and the finer, the more delicate, the subtler this indrawing becomes, the closer it is to this central point of consciousness. But from the point of view of philosophy, meditation and its experiences are not the ultimate goal--although they may help in preparing one for that goal. In that goal there is no kind of centre to be felt nor any circumference either--one is without being localized anywhere with reference to the body, one is both in the body and in the Overself. There is then no contradiction between the two.
