The mystery of the ages is man; each one of us. Patience is needed in order that the passage of time61 required for the bodily instrument to be altered or controlled is complete. Violent control is not as good as gentle control continuous and firmly unrelaxed. The Seeress of Prevorst found that a gentle current did her more good than a violent one would. Gentleness is better because an opposition current is always provoked, and of course if that which produces it is gentle, it will also be the same. This gives the unaccustomed student more time and gradual strength.
You are right in thinking that the essential principles of Theosophy are often stated without the use of that name, for it is the only universal fundamental system which underlies the religions of every age. The New Testament, rightly understood, teaches Theosophy, and we know that both Jesus and St. Paul were initiates. Of course, in Theosophy, as in any other Science, one understands more as one reads more, and I recommend you to read and digest such of our books as you can conveniently procure.

Then select the spot in the head where the Shushumna nerve goes. Never mind the location; call it the top of the head. Then pursue the same course. This will give some insight into spiritual minds. At first it is difficult, but it will grow easy by practice. If done at all, the same hour of each day should be selected, as creating a habit, not only in the body, but also in the mind. Always keep the direction of Krishna in mind: namely, that it is done for the whole body corporate of humanity, and not for one's self.
One instance will suffice. One may see pictures in the astral light through the back of the head or the stomach. In neither place is there any eye, yet we see. It must be by the power of seeing, which in the material body needs the specialized place or specializing organ known as the eye. We hear often through the head without the aid of the auricular apparatus, which shows us that there is the power of hearing and of transmitting and receiving sounds without the aid of an external ear or its inside cerebral apparatus. So of course all these things survive in that way. Any other view is grossly material, leading to a deification of this unreal body, which is only an image of the reality, and a poor one at that.
