ABSTRACT
We have finished a cursory review of the different steps in Râja Yoga, except the finer ones, the training in concentration, which is the aim, the goal, to which Râja Yoga will lead us. We see, as human beings, that all our knowledge which is called rational is referred to consciousness. I am conscious of this table, I am conscious of your presence, and so forth, and that makes me know that you are here, and that the table is here, and things I see, feel and hear, are here. At the same time, there is a very great part of my existence of which I am not conscious — all the different organs inside the body, the different parts of the brain, the brain itself; nobody is conscious of these things.
