... I strongly advise you to give up all yoga practices, which in almost all cases have disastrous results unless guided by a competent teacher. The concussions and explosions in your head are evidences that you are in no fit condition to try yoga practices, for they result from lesions of the brain, _i.e._, from the bursting of the very minute brain cells. I am glad you have written to me upon this matter, that I may have an opportunity of warning you. Also I advise you to discontinue concentration on the vital centres, which again may prove dangerous unless under the guidance of a teacher. You have learnt, to a certain degree, the power of concentration, and the greatest help will now come to you from concentration upon the Higher Self, and aspiration toward the Higher Self. Also if you will take some subject or sentence from the _Bhagavat Gîtâ_, and concentrate your mind upon that and meditate upon it, you will find much good result from it, and there is no danger in such concentration. * * * * * As to the question about the disintegration of the astral body and the length of time beforehand when it could be seen. My answer was not meant to be definite as to years, except that I gave a period of two years as a long one before the death of the physical body. There are cases--perhaps rare--in which five years before the death of the physical, a clairvoyant has seen the disintegration of the astral beginning. The idea intended to be conveyed is, that regardless of periods of time, if the man is going to die naturally (and that includes by disease), the corruption, disintegrating or breaking up of the astral body may be perceived by those who can see that way. Hence the question of years is not involved. Violent deaths are not included in this, because the astral in such cases does not disintegrate beforehand. And the way of seeing such a death in advance is by another method altogether. Death from old age--which is the natural close of a cycle--is included in the answer as to death by disease, which might be called the disease of inability to fight off the ordinary breaking up of the cohesive forces. * * * * * You cannot develop the third eye. It is too difficult, and until you have cleared up a good deal more on philosophy it would be useless, and a useless sacrifice is a crime of folly. But here is advice given by many Adepts: every day and as often as you can, and on going to sleep and as you wake, think, think, think, on the truth that you are not body, brain, or astral man, but that you are THAT, and "THAT" is the Supreme Soul. For by this practice you will gradually kill the false notion which lurks inside that the false is the true, and the true is the false. By persistence in this, by submitting your daily thoughts each night to the judgment of your Higher Self, you will at last gain light. * * * * *
