Thank you both for your valuable comments.
Just a short question to Lal:
Soontaneous birth is something that I usually mostly accounted for the Gandhabba state. But I heard something about Angels who are able to use a real human physical body sometimes to communicate with us. I say angels because I heard about it from a Christian context. It should be Deva, I assume.
But spontaneous birth can also mean that the physical body is born instantaneously (not Gandhabba), similar to how Angels can create one to use. I understand you, Lal, in this second way, when I read your writing.
Right?
