Progress

A disciple is like a new moon,
In reality no different than the full moon:
Its apparent imperfection is a sign of grateful increase.
Night by night the newmoon gives a lesson in gradualness:
With deliberation it says, “O hasty one,
Only step by step can one ascend to the roof.”
A skillful cook lets the pot boil slowly;
The stew boiled in a mad hurry is of no use.
[Mathnawi VI, 1208-1212]
