I would call that a sage-in-training
The experience of a sage really is non-dualistic, there's no mistaking it. People can lose awareness of their body in that blissful state, can forget to eat, even forget to breathe -- it doesn't matter much anymore. Many enlightened people leave the physical plane that way. (Don't let that scare you, though!
their consciousness goes off to non-physical realms for more adventures
)
To clarify -- the body-mind still has to live in the world of duality (and it goes on spontaneously and automatically, without a "you" (ego) having to run it and make choices), but consciousness itself has disidentified with the self and is nondualistic; Awareness aware of only itself, and not the contents of consciousness.
You also begin to see everything as yourself, because you're the Awareness that contains everything. Everything becomes incredibly beautiful, because intrinsically they are Divine by nature of Existence via God's Manifestation, and God is Infinite Love/Beauty.
I've had tiny glimpses into that state, and it really is that way, not just metaphoric. So all the spiritual work we do is well worth it in the end
