As the heat of a fire reduces wood to ashes, the fire of knowledge burns to ashes all karma. Nothing in this world purifies like spiritual wisdom. It is the perfection achieved in time through the path of yoga, the path which leads to the Self within.
No work stains an individual who is pure, who is in harmony, who is master of his life, whose soul is one with the soul of all.
