Before the pupil starts to study itself, the teacher himself studies him raja yoga information and determines a way to which the pupil should follow, i.e. plans the order of consecutive exercises, which are necessary for carrying out to the pupil. The exercise for different people cannot be same.
The purpose of raja yoga is to approach the person to the maximum consciousness, to prove an opportunity of a new condition of the consciousness similar to awakening after dream. The person does not know taste and sensation of this awakening, while his mind is still shipped in dream, the raja yoga aspires to make clear the idea of awakening, narrating about people, which have reached awakening, training the person to comprehend fruits of their idea and activity, which are absolutely not similar to result of activity of usual people.
Raja yoga concept deals with development of consciousness. It is the yoga of education of consciousness. The person practically studying raja yoga information gets consciousness of the "I", and together with it, he gets the unusual internal forces and ability to influence other people.
The raja yoga practice is in relation to the mental world of the person, to its consciousness, represents itself the same, that hatha-yoga in relation to the world physical. Hatha-yoga is the yoga of overcoming of a body, purchase of the control over a body and its functions. Raja yoga information provides overcoming of mind, i.e. illusory, wrong consciousness of the person, yoga of purchase of the control over consciousness.
The Raja yoga teaches the person to know himself in the first turn! It makes a basis of all philosophy of the world. Hatha yoga looks at a physical body as on imperfect and requiring in change for the best, is exact as also raja-yoga considers the mental device of the person at all as ideal, but requiring in change for the best and perfection.
The task of raja yoga information is statement of mind, the consciousnesses, similar to voice training at singers. The usual western idea does not understand necessity of statement of consciousness at all, considering, in general, that the usual consciousness is quite enough for the person, that he cannot have other consciousness. Raja yoga finds, that even very strong mind, as well as a strong voice, requires correct statement, decupling its forces, ability and productivity, forcing it to sound better, to distribute mutual relations of ideas, to cover for times more material.
The first that the raja yoga asserts is that the person does not know himself at all, that the idea of his forces is completely false and deformed. Misunderstanding is the main obstacle of the person in his way, the main reason of his weakness. Imagine the person, who does not know the body, his members, their number and relative position, does not know that he has two hands, two legs, one head, etc. It will be an exact copy of our attitude to the mental world. The mentality of the person, from the point of view of raja-yoga, is a system of the curved and blacked out glasses.
