スーフィー教の聖典 フィーヒ･マ･フィーヒより： ルーミー語録 談話四と二一　二二

If you plant a seed with no husk, it cannot grow, but if you bury it in the earth with its shell, then it germinates and becomes a great tree. So, form is a great and necessary principle, and without it our task fails and our purpose is not attained. Yes this principle is reality in the eyes of those who know reality and have become reality!
