Writing this message from the resting place or swami Vivekananda, and his guru Ramakrishna Paramahamsa. Non duality sounds cool only when you become the witness of your all actions, and when you become witness, you take actions which bring peace to your mind.. but when the non duality is being used to defend your own actions as a tool of justification than it becomes more like an external expression of thoughts which comes under duality which you tag it as non duality that simply means you are simply trying to play with words to justify your deeds as an act of validating your own existence. In summary; intellectual non-duality vs. lived non-duality are completely different thing
