To use a worn out analogy, think of this primordial principle as an ocean… all there is is an ocean of existence. You (the body-mind) are a fleeting wave which has no existence other than the movement of the ocean. So yes, of course, there is this phenomenal expression which we call you or me (that’s how I’m able to address you right now.) This is not denied (Buddhists call this the conventional self.) But it is not a separate, fixed, independent or inherently existing entity - such a thing does not exist.
Reflectively we envisage ourselves as noun-like entities in a world of other noun-like entities and thus have sense of separation and fragmentation. When the divide and abstract tendency of the reflective mind is absent the primordial ‘happening’ of existence (the universal verb if you like) is once more unobscured. And it can dawn that right now there is nothing other than THAT.
