Simply contemplate the question “What is the world?” By
contemplate, I mean to simply form the question in your mind. Don't think about
it. Just present the question and relax your awareness as much as possible.
That’s the “how.”
Experiencing unity is a bit like getting a joke. The "getting" of a joke is what causes the laughter. In a sense, the getting is the laughter. But we don't laugh because we have analyzed the joke and come to understand it; we laugh because the joke exposes something about ourselves. It removes the seriousness of the boundaries that we believe in and live by. It reveals that they are absurd and therefore funny. The same is true of the beliefs that cause us to experience boundaries. In a very real sense, beliefs are the creators of the experience of boundaries. They are absurd, even if at times useful, fictions, but only experienced as absurd when we see that they are absurd and worthy of a good laugh.
Every description, every name, every belief -- good or bad -- every concept, creates boundaries where there are in fact no boundaries at all. Even to say “I” instantly imposes a boundary upon what is actually a unified field of being. To say “I” instantly creates what is not “I.” “Big” is always in relationship to “small,” “up” in relationship to “down,” “good” in relationship to “bad,” “heads” of a coin in relationship to “tails.” Words imply that these opposites exist separately from one another, but they do not. They are simply different ways of looking at the same thing. You cannot have the crest of a wave without also having its trough; they are in reality one dynamic process.
As I have often said, each thing is its total environment. Remove the environment in which anything exists, and the thing will also not exist, which is to say that there is no such thing as a thing. To call something a thing, or to give it a name, is to conceptually impose boundaries upon it where they do not actually exist. A tree does not exist independently of its environment; it is its total environment. It takes a cosmos to produce a tree -- no cosmos, no tree. To say “tree” implies the entire cosmos. The same is true of you.
