It is really surprising that some people consider themselves to be too weak for spiritual practice, while actually they are not so. An ordinary man has within him the same power and the same soul-force that a saint has.
The only difference between them is that the sage has torn off the coverings round his soul while the others are just like a silkworm in the cocoon.
And if one resolves firmly to throw off these coverings no power on earth can stop him. What is required for spiritual growth of man is only an iron will. When it is there, the goal is just in sight. If we have these two things there can be absolutely no chance of failure.
