The outward form of dervishhood is a tattered robe and a shaven head; its truth is a living heart and a dead ego.
ظاهر درویشی جامه ژنده است و موی سترده و حقیقت آن دل زنده و نفس مرده
Zâhir-i dervîşî câme-i jende est ü mûy-i sütürde ve hakîkat-i ân dil-i zinde vü nefs-i mürde
Saadi, Gulistan, Chapter II, story 46 (1258).
Saadi first lists the outside.
A tattered robe, a shaven head.
Then the inside.
A living heart, a dead ego.
A costume is put on in a day.
The other takes a lifetime.
Clothes do not give a person away.
No one displays
his heart in the marketplace.
Look at what you are shown.
Then ask yourself
what lies where nothing is shown.
