The face of truth is open,
The eyes of truth are bright,
The lips of truth are ever closed,
The head of truth is upright.

The breast of truth stands forward,
The gaze of truth is straight,
Truth has neither fear nor doubt,
Truth has the patience to wait.

The words of truth are touching,
The voice of truth is deep,
The law of truth is simple:
All that you sow you reap.

The soul of truth is flaming,
The heart of truth is warm,
The mind of truth is clear,
And firm through rain or storm.

Facts are but its shadows,
Truth stands above all sin;
Great be the battle in life,
Truth, in the end, shall win.

The image of truth is Christ,
Wisdom’s message its rod;
A sign of truth is the cross,
The soul of truth is God.

Life of truth is eternal,
Immortal is its past,
Power of truth will endure,
Truth shall hold to the last.

(and here is a separate quote of his about speaking truth: “Oppressors are all afraid of me because I speak the truth that can set men free.”)

** There is possible evidence that Hazrat Inayat Khan, a Sufi poet, might have written the original poem, and was quoted by Ali in an interview. I have not found a book with the record piece by Khan, only websites indicating this, but as a historian, it is important to me that I mention the information I newly read. 

The message of the poem stands firm, just as does Truth.
