The honey of life is hope. If the knowledge of God does not give hope to attain the divine bliss which is attained in life, that knowledge is of no use. Man may believe in God for years, yet may not be benefitted by spiritual bliss; for spiritual bliss is not only in believing, but also in knowing God. Buddhi, which is subtle reasoning, is the path which leads to the goal. The absence of that keeps a person in obscurity. As the sun is the source of light which shows outward things in life, so buddhi is the inner source of light which enables the person to see life clearly, inwardly and outwardly. The true aim of the disciples of Buddha has not been only to admire Buddha, his name or his ideal, but to take Buddha as an example before them. Their idea is the secret of Sufism.
