Non-dualism is certainly something that can greatly help a human being. The main difference is that generally Nondualism describes a form of unity; a "One" such as Advaita Vedanta and Mahayana Buddhism and I'm on the more Theravada/RQM take of non-duality in "Zero" instead of "One". It's corelations without corelata.

The best example I know is the dictionary. Each word's meaning arises depending on other words which gain their meaning through other words creating a complex web which despite being limited in scope, it is without end or source. For a significant portion I'm behind non-dualism except for that primary difference.

I think the quotes are the most efficient way to capture the essence of a person's philosophy. So I invite you to try these links.
