Truth alone can succeed...

Truth alone can succeed; falsehood is a waste of time and loss of energy.

Bowl of Saki, by Hazrat Inayat Khan
Commentary by Pir-o-Murshid Inayat Khan:

Falsehood, whatever its apparent success, has its limitations and its end. For at every step the false person will feel falseness; and with every step a person takes towards falsehood, he will feel his feet growing heavier and heavier when he encounters the truth, while those who walk towards the truth will feel their feet becoming lighter with every step they take.

Truth is the divine element in man. Truth is every soul's seeking. Therefore as soon as the clouds of illusion are scattered, that which man now begins to see is nothing but the truth which has been there all the time. He finds that the truth was never absent; it was only covered by clouds of illusion.

By changing his own nature, by making himself more truthful, he disperses the clouds of falsehood within and without, and begins to see life as it really is both inwardly and outwardly. From this time onwards, the meaning of religion becomes clear. One begins to understand what the great teachers have taught. Then one becomes tolerant to the various religions. Nothing seems strange any more. Nothing surprises. For now one begins to know the innermost nature of man; one sees the cause behind every action.

People speak about truth and falsehood, but once the mystic has reached the truth, all is truth to him; then everything is a phenomenon of truth, a picture of truth. For instance, a person looking at a picture may distinguish light and shade, but another instead of speaking of light and shade, will say, 'This is a portrait of so and so, it is a very good picture, exactly like him.' Truth is like this; and so to a mystic the whole of life is a picture of the divine Beloved.
