Along such lines you can learn to bring into control your mind, to discipline your vagrant thought, and thus to reach illumination. One word of warning. You cannot do this, while you are trying meditation with a seed. until you are able to cling to your seed definitely for a considerable time, and maintain throughout an alert attention. It is the emptiness of alert expectation. not the emptiness of impending sleep. If your mind be not in that condition, its mere emptiness is dangerous. It leads to mediumship, to possession, to obsession. You can wisely aim at emptiness, only when you have so disciplined the mind that it can hold for a considerable time to a single point and remain alert when that point is dropped. The question is sometimes asked: “Suppose that I do this and succeed in becoming unconscious of the body; suppose that I do rise into a higher region; is it quite sure that I shall come back again to the body? Having left the body, shall I be certain to return?” The idea of non-return makes a man nervous. Even if he says that matter is nothing and Spirit is everything, he yet does not like to lose touch with his body and, losing that touch, by sheer fear, he drops back to the earth after having taken so much trouble to leave it. You should, however, have no such fear. That which will draw you back again is the trace of your past, which remains under all these conditions. The question is of the same kind as: “Why should a state of Pralaya ever come to an end, and a new state of Manvantara begin?” And the answer is the same from the Hindu psychological standpoint; because, although you have dropped the very seed of thought, you cannot destroy the traces which that thought has left, and that trace is a germ, and it tends to draw again to itself matter, that it may express itself once more. This trace is what is called the privation of matter— samskara. Far as you may soar beyond the concrete mind, that trace, left in the thinking principle, of what you have thought and have known, that remains and will inevitably draw you back. You cannot escape your past and, until your life-period is over, that samskara will bring you back. It is this also which, at the close of the heavenly life, brings a man back to rebirth. It is the expression of the law of rhythm. In Light on the Path, that wonderful occult treatise, this state is spoken of and the disciple is pictured as in the silence. The writer goes on to say: “Out of the silence that is peace a resonant voice shall arise. And this voice will say: ‘It is not well; thou hast reaped, now thou must sow.’ And knowing this voice to be the silence itself, thou wilt obey.”
