^^This title attracts readers because of the words unification and purification. At least for me it was. In many ways and in many things unification and purification takes place which we don't see.
Like rain that clouds cry
^^I also like the repetition of this line-there is a soothing effect to it when its been read. A calming statement which brings the reader back to a state of ease. I also can see the two ponds as two people from afar falling, growing and fading together. There is much behind this poem than what grabs the mind...I like it!
