Life and yoga are not two but one thing. Life, at least as we experience it, is a concealed yoga. Yoga as the yogin experiences it is life taken to its utmost.
The yoga opens the doors of knowledge, true knowledge for us so that we become aware of the truth of our own self and the truth of the world around us. This truth and knowledge are liberating.
In our secret self we too belong to this world that exists on the heights of luminous mentality. Our strivings are an effort to reach out to the realms from where we descended.
... what about survival of the fittest, what about competition and strife that abound in our everyday life? What alternative fuel to drive human nature does yoga provides?
We have come a long way from the narrow conception of charity restricted to the giving of a little of what we have in excess to the unfortunate ones that life brings in our way! And what we say of material riches must be said of spiritual wealth also.
... in most cases the absorbing interest in fulfillment of vital desires as well as the time and energy needed just for maintaining the framework of the family life leaves little room and time for spiritual self-growth which demands a greater and greater one-pointedness.
