The method of attainment is to endeavor always to make others happy and by experiencing happiness in the happiness of others. In the terms of the Sufi it is "Suluk". Any selfishness prevents us from appreciating another’s happiness and therefore we shall be kept back, for the happiness of others is the gate to our own happiness. Real happiness is entering the gate. We must feel satisfaction in another’s satisfaction and our appetite must be satisfied even when the food is eaten by another. That is the first lesson that sages learn. But it is not necessary for us to be saints and sages to learn it. If we only knew what happiness it is when we have given joy to others, we would then realize . . . . . If a person needs a certain thing and we can supply it, we should be happy, however small the thing may be.
