Sri Aurobindo
Letters of Sri Aurobindo
Volume III - Part 2
From what he writes it is apparent that he has a capacity [for Yoga], and it is probable that he would have made more progress if he had not shut the door that was opening. Evidently, he made a mistake when he stopped the visions that were coming. Vision and hallucination are not the same thing. The inner vision is an open door on higher planes of consciousness beyond the physical mind which gives room for a wider truth and experience to enter and act upon the mind. It is not the only or the most important door, but it is one which comes readiest to very many if not most and can be a very powerful help. It does not come easily to intellectuals as it does to men with a strong life-power or the emotional and the imaginative. It is true that the field of vision, like every other field of activity of the human mind, is a mixed world and there is in it not only truth but much half-truth and error. It is also true that for the rash and unwary to enter into it may bring confusion and misleading inspirations and false voices, and it is safer to have some sure guidance from those who know and have spiritual and psychic experience. One must look at this field calmly and with discrimination, but to shut the gates and reject this or other supraphysical experiences is to limit oneself and arrest the inner development.
