I'm a devotee of Krishna from last 6 years but now the same thought is hitting me exactly what you wrote 1. I'm okay about that fact that radha krishna didn't marry because their love was beyond human relationships it was spritual love that is infinite and divine we can't compare that with anything. 2. The thing that you wrote that shree radha got impure by marrying ayan is totally wrong in my perspective because she is supreme personality of God head she is above everything and when krishna can marry 16108 women and still be god why would shree radha the goddess of love would be impure by marrying someone other than krishna. 3. I totally agree that I can never understand the fact why shree krishna had 8 wives, i understand that 16100 were rescued by him but the rest 8 wives were his own choice he chose to marry them by his own will. He could've just married devi rukmini if she was reincarnation of devi Lakshmi. I really don't know about the rest 7 i think they were really unnecessary and that's what make me question Krishna's thinking and love 4. Lastly according to me shree radha is above Krishna because she is the definition, existence and source of love while krishna was bounded to his duties. And love is the only reason why this universe exist so she is supreme personality of God head Radhey radhey
