A person who is highly evolved and whose outward conduct, which alone manifests to people's view, may appear altogether contrary to their own way of looking at things, may be accused of being a materialist or an unbeliever, or someone who is far from God and truth. Yet we do not know: sometimes appearances are merely illusions; behind them may be hidden the deepest religious devotion and the highest ideal, of which we know very little. For the Sufi, therefore, the best thing is to respect man and his belief, whatever it may be; his ideal, whatever it may be; and his way of looking at life, even if it be quite different from our own way. This spirit of tolerance, when developed, will bring about the brotherhood which is the essence of religion and the want of the day.
