I really love the message here, and the fact that you placed this under 'love poems' (instead of life) shows praying is not just a part of life or routine, but it is something bigger.
Just some tweaks here and there, and this piece would truly shine at its best:
"Watching your silent praying"
I suggest: "Watching you silently praying"
"If you are making one quite pray
Please mention I want to stay"
Do you mean 'quiet' instead of quite?
I suggest you revise this to: "If you are making one quiet pray'r.."
"Crossing mind a breast with invisible lines"
abreast is one word :)
"Suddenly I feel a spirit lifting me
Seems right and right to be
I am praying with you, won't stop
Inside me a glow is building up"
Now that^^is beautifully written. You just captured that feeling that we feel when praying. Amazing job. Keep writing, sir
