“You attain to knowledge by argument;
You attain a craft or skill by practice;
If voluntary poverty's your choice,
companionship's the way, not hand or tongue.
The knowledge of it passes soul to soul,
not by way of talk or reams of notes.
Its signs are writ upon the seeker's heart,
yet still the seeker cannot ken those signs
until his heart becomes exposed to light
Then God reveals His: Did We not expose? [Qur'an 94:1]
for We've exposed the chambers of your breast
and placed the exposition in your heart”
