MASNAVIII:566-8

The reflections cast from good friends are needed until you become, without the aid of any reflector, A drawer of water from the sea.
Know that at first the reflection is jus imitation, but when it continues to recur, It turns into direct realization of truth.
Until it has become realization, Do not part from the friends who guide you –
Do not break away from the shell until the raindrop has become a pearl.
