The Stone Philosophical

Make pure thy sense till thou art dust
That out of dust thy grass may grow:
When thou art hay, then burn thou must,
Thy fire most mightily must glow.
And when at last thy dust is burned,
Thy ash to Wisdom’s Stone is turned.
Then live by the Stone’s grace.
This stone it is of noble race.
The Phoenix by its lightning flashes
Will burn till he is turned to ashes,
Then rises younger from the flame.
This Stone the Grail they name.
