Many spiritual people and teachers talk about Non-Duality. However, few grasp the reality that it cannot be directly talked about, but only pointed to (called pointing out instructions). Thus, it says in the Tao Te Ching: “Those who know don’t talk. Those who talk, don’t know.”
People with Non-Dual awareness are at one with the world. That state of being is not something that is taught through words, but is acquired through right action. Such a person is not concerned how others might perceive him or her. Being free of the need to conform to others’ judgments, Non-Duality is taught by example and not by preaching or prescribing exercises or requiring rigid adherence to a curriculum.
