What human thinking mind is seeking is wholeness, which is everything, which is why it can never be found! There is only just whatever is appearing, however it’s appearing. This leaves nothing out. Everything, all that is, simply as it is.
Nonduality is One without a second. And that One IS everything, which literally leaves nothing out. But human mind sees apparent separation and so tries to get wholeness for itself. But this is not just crazy and nonsensical, but impossible. No separation leaves no one outside of all that is to get anything. All is simply Life, as it is. There is nothing hidden, nothing more… simply THIS.
