There is nothing contradictory here. The beauty of the title is to impress upon the listener the essential nature of the liberated mind and all of existence as non-dual. It isn't one or the other because the further down you go, what emerges vanishes instantaneously, simultaneously. Zen and Vajrayana practices can be an effective tool but I see more faulty thinking in its practitioners than people who stick to Sravakayana (Theravada + surviving canon of the other Early Buddhist schools).
