The mind becomes stable only in the association with good people. 153 The great mantras, the great philosophies, everything we can understand in association with the good people. They tell us their experience and guide our way. 154 Let us try to find out the element that is invisible. There lies the secret. We cannot just hold it exclusively with us. That element is all-pervading. 155 He who calls himself a learned person is a fool. The element that we have been talking about is beyond logic. So no one can explain it logically. One who does not have any ego can realise that element. The moment that element is realised, the identity of the person who realises gets merged with that element. 156
