Before you begin to practise, clear your mind of all doubts. Fight and reason and argue, and when you have established it in your mind that this and this alone can be the truth and nothing else, do not argue any more; close your mouth. Hear not argumentation, neither argue yourself. What is the use of any more arguments? You have satisfied yourself, you have decided the question. What remains? The truth has now to be realized, therefore why waste valuable time in vain arguments? The truth has now to be meditated upon and every idea that strengthens you must be taken up and every thought that weakens you must be rejected. The _Bhakta_ meditates upon forms and images and all such things and upon God. This is the natural process, but a slower one. The _Yogi_ meditates upon various centres in his body and manipulates powers in his mind. The _Jnâni_ says the mind does not exist, neither the body. This idea of the body and of the mind must go, must be driven off; therefore it is foolish to think of them. It would be like trying to cure one ailment by bringing in another. His meditation therefore is the most difficult one, the negative; he denies everything, and what is left is the Self. This is the most analytical way. The _Jnâni_ wants to tear away the universe from the Self by the sheer force of analysis. It is very easy to say, “I am a _Jnâni_,” but very hard to really be one. “The way is long; it is, as it were, walking on the sharp edge of a razor, yet despair not. Awake, arise, and stop not until the goal is reached,” say the Vedas.
