The power of generosity is one of the greatest powers in the universe. The power of generosity is unimaginable. Generosity is the very basis of spiritual advancement: it is karma in motion, creating benefit. That is why all the great masters exemplify generosity—the power of sacrifice. In Kabbalah, that is the power of the sephirah Chokmah: love as sacrifice, the power of giving. It is a generosity of spirit, a generosity of heart.
True generosity is most accurately summarized as thinking of others before yourself. It is the most fundamental basis of real spirituality.
