This method is to be found through the ancient psychological discipline and practice of Yoga. In the past, it has been attempted by a drawing away from the world and a disappearance into the height of the Self of Spirit. Sri Aurobindo teaches that a descent of the higher principle is possible which will not merely release the spiritual Self out of the world, but release it in the world, replace the mind's ignorance or its very limited knowledge by a supramental Truth-Consciousness which will be a sufficient instrument of the inner Self and make it possible for the human being to find himself dynamically as well as inwardly and grow out of this still animal humanity into a diviner race. The psychological discipline of Yoga can be used to that end by opening all the parts of the being to a conversion or transformation through the descent and working of the higher still concealed supramental principle. This, however, cannot be done at once or in a short time or by any rapid or miraculous transformation.
Many steps have to be taken by the seeker before the supramental descent is possible.
Man lives mostly in his surface mind, life and body, but there is an inner being within him with greater possibilities to which he has to awake - for it is only a very restricted influence from it that he receives now and that pushes him to a constant pursuit of a greater beauty, harmony, power and knowledge. The first process of Yoga is therefore to open the ranges of this inner being and to live from there outward, governing his outward life by an inner light and force. In doing so he discovers in himself his true soul which is not this outer mixture of mental, vital and physical elements but something of the Reality behind them, a spark from the one Divine Fire. He has to learn to live in his soul and purify and orientate by its drive towards the Truth the rest of the nature. There can follow afterwards an opening upward and descent of a higher principle of the Being.
