Prana
The theory of creation is that matter is subject to five conditions: ether, luminous ether, gaseous, liquid, and solid. They are all evoked out of one primal element, which is very finest ether.
The name of the energy in the universe is Prana, which is the force residing in these elements. Mind is the great instrument for using the Prana. Mind is material. Behind the mind is Atman which takes hold of the Prana. Prana is the driving power of the world, and can be seen in every manifestation of life. The body is mortal and the mind is mortal; both, being compounds, must die. Behind all is the Atman which never dies. The Atman is pure intelligence controlling and directing Prana. But the intelligence we see around us is always imperfect. When intelligence is perfect, we get the Incarnation–the Christ. Intelligence is always trying to manifest itself, and in order to do this it is creating minds and bodies of different degrees of development. In reality, and at the back of all things, every being is equal.
Mind is very fine matter; it is the instrument for manifesting Prana. Force requires matter for manifestation.
The next point is how to use this Prana. We all use it, but how sadly we waste it! The first doctrine in the preparatory stage is that all knowledge is the outcome of experience. Whatever is beyond the five senses must also be experienced in order to become true to us.
Our mind is acting on three planes: the subconscious, conscious, and superconscious. Of men, the Yogi alone is superconscious. The whole theory of Yoga is to go beyond the mind. These three planes can be understood by considering the vibrations of light or sound. There are certain vibrations of light too slow to become visible; then as they get faster, we see them as light; and then they get too fast for us to see them at all. The same with sound.
How to transcend the senses without disturbing the health is what we want to learn. The Western mind has stumbled into acquiring some of the psychic gifts which in them are abnormal and are frequently the sign of disease. The Hindu has studied and made perfect this subject of science, which all may now study without fear or danger.
Mental healing is a fine proof of the superconscious state; for the thought which heals is a sort of vibration in the Prana, and it does not go as a thought but as something higher for which we have no name.
Each thought has three states. First, the rising or beginning, of which we are unconscious; second, when the thought rises to the surface; and third, when it goes from us. Thought is like a bubble rising to the surface. When thought is joined to will, we call it power. That which strikes the sick person whom you are trying to help is not thought, but power. The self-man running through it all is called in Sanskrit Sutratma, the “Thread-self”.
The last and highest manifestation of Prana is love. The moment you have succeeded in manufacturing love out of Prana, you are free. It is the hardest and the greatest thing to gain. You must not criticise others; you must criticise yourself. If you see a drunkard, do not criticise him; remember he is you in another shape. He who has not darkness sees no darkness in others. What you have inside you is that you see in others. This is the surest way of reform. If the would-be reformers who criticise and see evil would themselves stop creating evil, the world would be better. Beat this idea into yourself.
