12. Experiences of the Inner and the Cosmic Consciousness
In my last letter I had postponed the explanation of your third experience. What you have felt is indeed a touch of the Self, not the unborn Self above, the Atman of the Upanishads, for that is differently experienced through the silence of the thinking mind, but the inner being, the psychic supporting the inner mental, vital, physical being, of which I have spoken. A time must come for every seeker of complete self-knowledge when he is thus aware of living in two worlds, two consciousnesses at the same time, two parts of the same existence. At present he lives in the outer self, but he will go more and more inward, till the position is reversed and he lives within in this new inner consciousness, inner self and feels the outer as something on the 
surface formed as an instrumental personality for the inner’s self-expression in the material world. Then from within a Power works on the outer to make it a conscious plastic instrument so that finally the inner and the outer may become fused into one. The wall you feel is indeed the wall of the ego which is based on the insistent identification of oneself with the outer personality and its movements. It is that identification which is the keystone of the limitation and bondage from which the outer being suffers, preventing expansion, self-knowledge, spiritual freedom. But still the wall must not be prematurely broken down, because that may lead to a disruption or confusion or invasion of either part by the movements of the two separated worlds before they are ready to harmonise. A certain separation is necessary for some time after one has become aware of these two parts of the being as existing together. The force of the yoga must be given time to make the necessary adjustments and openings and to take the being inward and then from this inward poise to work on the outer nature.
This does not mean that one should not allow the consciousness to go inward so that as soon as possible it should live in the inward world of being and see all anew from there. That inward going is most desirable and necessary and that change of vision also. I mean only that all should be done by a natural movement without haste. The movement of going inward may come rapidly, but even after that something of the wall of ego will be there and it will have to be steadily and patiently taken down so that no stone of it may abide. My warning against allowing the sleep world to encroach on the waking hours is limited to that alone and does not refer to the inward movement in waking concentration or ordinary waking consciousness. The waking movement carries us finally into the inner self and by that inner self we grow into contact with and knowledge of the supraphysical worlds, but this contact and knowledge need not and should not lead to an excessive preoccupation with them or a subjection to their beings and forces. In sleep we actually enter into these worlds and there is the danger, if the attraction of the sleep consciousness is too great and encroaches on the waking consciousness, of this excessive preoccupation and influence.
It is quite true that an inner purity and sincerity, in which one is motived only by the higher call, is one’s best safeguard against the lures of the intermediate stage. It keeps one on the right track and guards from deviation, until the psychic being is fully awake and in front and, once that happens, there is no further danger. If, in addition to this purity and sincerity, there is a clear mind with a power of discrimination, that increases the safety in the earlier stages. I do not think I need or should specify too fully or exactly the forms the lure or pull is likely to take. It may be better not to call up these forces by an attention to them which may not be necessary. I do not suppose you are likely to be drawn away from the path by any of the greater perilous attractions. As for the minor inconveniences of the intermediate stage, they are not dangerous and can easily be set right as one goes by the growth of consciousness, discrimination and sure experience.
As I have said, the inward pull, the pull towards going inward is not undesirable and need not be resisted. At a particular stage it may be accompanied by an abundance of visions due to the growth of the inner sight which sees things belonging to all the planes of existence. That is a valuable power helpful in the sadhana and should not be discouraged. But one must see and observe without attachment, keeping always the main object in front, realisation of the inner Self and the Divine – these things should only be regarded as incidental to the growth of consciousness and helpful to it, not as objects in themselves to be followed for their own sake. There should also be a discriminating mind which puts each thing in its place and can pause to understand its field and nature. There are some who become so eager after these subsidiary experiences that they begin to lose all sense of the true distinction and demarcation between different fields of reality. All that takes place in these experiences must not be taken as true – one has to discriminate, see what is mental formation or subjective construction and what is true, what is only suggestion from the larger mental and vital planes or what has reality only there and what is of value for help or guidance in inner sadhana or outer life.
