Come into being vs be brought into being

One difference I see is that "The plan came into being" is in active voice while "the plan was brought into being" is in passive voice.
I will still leave this to experts to answer, though.

Neither of them sounds natural to me. Do you mean that the plan was devised or that it was implemented?

voynichThe plan came into being

This almost sounds like the plan materialized by itself from nothing, as if by magic. The reader will take the meaning correctly, though, if you provide the right context.

voynichthe plan was brought into being

This sounds like someone or some group made the plan come into being.

I meant "devised".

Neither of them sounds natural to me.

I googled "The plan came into being" and got over 100000 hits. Then, I judged that the sentence was a natural English sentence("The plan was brought into being" got only 3 hits though). How do I think it of?

voynichThe plan came into being ... over 100000 hits ... The plan was brought into being ... only 3 hits

I find this astonishing. I expected a difference, but not such a dramatic one.
