Nonduality is a philosophical concept that emphasizes the interconnectedness of all things, suggesting that distinctions between self and other, or subject and object, are ultimately illusory. It posits that reality is a unified whole, where dualistic perceptions, such as good and bad or self and world, are seen as mental constructs rather than absolute truths. In various spiritual traditions, including Buddhism and Advaita Vedanta, nonduality is often explored as a means to achieve deeper understanding and enlightenment. Practitioners may engage in meditation or self-inquiry to dissolve the sense of separation and experience a profound sense of oneness with existence.
