Where I see you mistaken I will speak, to warn my Brother who temporarily knows not. For did I not call on the bugle, perhaps other things might switch him off to where perhaps for the time he would be pleased, but would again be sorry, and then when his mistake was plain he would justly sigh to me across dark centuries of separation that I had been false to my duty of warning. As ever, Z. * * * * * The new plane to which the soul may go, referred to in this letter, is the astral plane. It is the plane next above the material one, and consists of a subtile order of matter. When a student turns his attention to the higher life and desires intensely to find the way, his soul has begun to awaken and to speak. It has heard the voice of the spirit. Then the inner senses begin to unfold, at first ever so gently, so tenderly, we scarce hear their report. But the soul has then turned its attention to the astral plane, that being the next one to be learned on the way upward; its energy is transferred from the material plane to this one, and we have an influx of many confused dreams and strange experiences, awake and asleep. These may or may not continue; all depends upon the individual soul and upon Karma. It is a most confusing plane, and, generally speaking, we may say that those students are more fortunate who make a marked degree of progress in spiritual things without having any conscious experience of the astral plane. For then they can later on learn it _from above_, instead of from below, and with far less danger to themselves. The whole must be known, but we may progress in various ways, even by discontinuous degrees, only then we must go back later on, to what we passed by. Such a going back does not imply detriment or loss of degree, for such cannot be lost when once gained in reality. With regard to the astral plane being a more subtile order of matter, this truth is often denied by clairvoyants and untrained seers. They do not distinguish between the psychic senses and the spiritual. They can see through gross matter, such as a wall, the human body, and so forth, as if it were glass, but they cannot see through astral substance, and hence they believe its forms and all the pictures and shapes in the astral light to be real. Only the adept sees through these illusions, which are far more powerful because composed of a subtile order of matter: subtile energies, fine forces have a highly increased rate of power over grosser ones. The adept has at his command the rate of vibration which dispels them or drives them asunder. In speaking of the astral plane, I mean the lower soul plane, and not that higher and purified quality which the author of _Light on the Path_ calls the "divine astral." By anxiety we exert the constrictive power of egoism, which densifies and perturbs our magnetic sphere, rendering us less permeable to the efflux from above. J. N. VII. DEAR JASPER:
