And a man said, "Speak to us of Self-Knowledge."
And he answered, saying:
Your hearts know in silence the secrets of the days and the nights.
But your ears thirst for the sound of your heart's knowledge.
You would know in words that which you have always know in thought.
You would touch with your fingers the naked body of your dreams.
And it is well you should.
The hidden well-spring of your soul must needs rise and run murmuring to the sea;
And the treasure of your infinite depths would be revealed to your eyes.
But let there be no scales to weigh your unknown treasure;
And seek not the depths of your knowledge with staff or sounding line.
For self is a sea boundless and measureless.
Say not, "I have found the truth," but rather, "I have found a truth."
The type of wisdom that Gibran is referring to, is of unmeasurable quality. Most individuals who are experiencing self-knowledge and the inner peace that can be found with that realization, have truly found a treasure which is so deeply personal, it is a treasure to behold, not weighed. No earthly scales exist because self-knowledge is so deeply personal and relevant, the value comes only from the individual who sees it within.
