''Telepathy, clairvoyance, clairaudience, presentiment, thought-reading, character-reading and many other modern discoveries are very ancient powers of the mind which have been left undeveloped, and they all belong to the manas. The development of the sixth sense has never formed part of human training. In a future age it will undoubtedly take a place in the necessary preliminary training of the human instrument. Meanwhile there is no reason why the mind should not be trained to give a correct report to the intellect so that our thought may start with absolutely correct if not with full impressions.''
