All Life Is Yoga: The Inward Movement In Yoga. Sri Aurobindo

"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." – Sri Aurobindo
