To understand the concepts of non-dual view is in no way the same as to have realized them as the reality of body, speech, and mind. In fact, without complimentary practice and realization, this can become a severe impediment to actualizing the meaning of the very same words.
While it is possible to form a conceptual contrivance of non-duality, this will not release oneself from suffering—or release oneself from the embodied and enworlded belief in a self! Nor will it allow one to truly become a refuge to others suffering the same. Instead, one can easily end up with an edifice of contrivance whose buttresses support and uphold the city of delusion.
This is so terribly sad because an apartment in the city of delusion always comes with the sofa and chairs of suffering and a bed called death. Happily, over lifetimes, suffering will lead such spiritual posing back to the doorstep of authentic practice which makes real (realizes) the truth of non-duality in body, speech, mind, qualities, activities ... embodied and enworlded. - t.k., recent talks
