What is spiritual attainment? Spiritual attainment is conviction. A man may think, "Perhaps it is so"; he may think about the best doctrine or about the highest idea that there is, and he will think, "it is so-perhaps." But there is "perhaps" attached to it. Then there is another person who cannot use the word "perhaps" because he does not think about it; he cannot say, "It may be so" when he knows that it is so. When a person arrives at the stage where the knowledge of reality becomes his conviction, then there is nothing in the world that will change it. If there is anything to attain to, it is that conviction which one can never find in the world outside; it must rise from the depth of one's own heart.
