Someone sent me a piece of prose/poetry which I really liked..though I don't know who has written it

Here are some of my favorite lines from that excerpt (the one in bold is my most fav) -

"For even as love crowns you so shall he crucify you.
Even as he is for your growth so is he for your pruning.
Even as he ascends to your height and caresses your tenderest branches that quiver in the sun,
So shall he descend to your roots and shake them in their clinging to the earth.
All these things shall love do unto you that you may know the secrets of your heart, and in that knowledge become a fragment of Life's heart"

"But if in your fear you would seek only love's peace and love's pleasure,
Then it is better for you that you cover your nakedness and pass out of love's threshing-floor,
Into the season-less world where you shall laugh, but not all of your laughter, and weep, but not all of your tears."

"Love gives naught but itself and takes naught but from itself.
Love possesses not nor would it be possessed
For love is sufficient unto love."

"And think not you can direct the course of love, if it finds you worthy, directs your course.
Love has no other desire but to fulfill itself.
But if you love and must needs have desires, let these be your desires:
To melt and be like a running brook that sings its melody to the night.
To know the pain of too much tenderness.
To be wounded by your own understanding of love;"
