I was just surprised, I don't know what you are? Sometimes you are my sister

I was just surprised, I don't know what you are? Sometimes you are my sister, Sometimes you are my kissable mother, You are my sultan when you keep quiet, When you talk you are my slave, You are my endless suffering, There is my horizon, You are here with me, You are my circle of infinity that surrounds me like a soul, I am desperate, You are my solution. I was just surprised, I don't know what you are?
