From Sufism’s Sacred Fihi ma Fihi: Discourse of Rumi, 4, 21 and 22, Part 1 of 2

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!
