That the caste system must be abolished if the Hindu society is to be reconstructed on the basis of equality, goes without saying. Untouchability has its roots in the caste system. They cannot expect the Brahmins to rise in revolt against the caste system. Also we cannot rely upon the non-Brahmins and ask them to fight our battle.
We never look deeply into the quality of a tree; we never really touch it, feel its solidity, its rough bark, and hear the sound that is part of the tree. Not the sound of wind through the leaves, not the breeze of a morning that flutters the leaves, but its own sound, the sound of the trunk and the silent sound of the roots.
A beginner must look on himself as one setting out to make a garden for his Lord's pleasure, on most unfruitful soil which abounds in weeds. His Majesty roots up the weeds and will put in good plants instead. Let us reckon that this is already done when the soul decides to practice prayer and has begun to do so.
