Buddha Nature/Mind (big letter M) is present everywhere.
That's a pretty big "if".
Here's another one. IF Buddha nature is the potential to achieve enlightenement, then it is not everywhere, but is confined to sentient beings. I don't think a rock has karma in the same sense we do. If a rock does not experience the results of my actions (it does not suffer and is not pleased by what I do) this casts doubt on the idea that I and the universe are one.
Bear in mind, it might be the case that:
I and the universe are not one
I and the universe do not differ
both at the same time, with the truth being some middle path
