Based on Chapter 14, what is the path to achieving the state of non-duality or 'oneness'?

The path to achieving oneness involves a fundamental shift in perception, guided by a Guru's wisdom. According to Chapter 14, one must first recognize that the intellect establishing duality is pure ignorance. The key is to surrender to the single essence that is the same in your own body as it is in the entire universe. This requires turning away from ignorance and pushing away the delusion of Maya. The text advises one to 'See Me alone in everything' and control one's vision to eliminate the sense of difference. By abandoning attributes like name, form, and action, and purifying the mind through a Guru's teachings, one can merge into the state of non-duality, much like pure water poured into pure water becomes indistinguishably one.
