Mevlana Rumi and being one with the Beloved

I used to think that there were no friends left for me in the whole universe. Then I abandon myself and I realized all the strangers became my friends…One who exists in his non-existence does not know non-existence while he exists…Strangers to this state are unaware of the pleasure of communion with the Beloved... How would one who has strangers as friends ever know?
Once people become aware of each other, doubt and critics of self will arise, and the result will be a growing interest in the interpretation of knowledge. How do we know that we know?...
