Integration is difficult unless the components were formed with integration in mind. To express a unitary view, all you need is to express your understanding of oneness, and all that it contains, in thought, word, and deed. With diligence, you can achieve full expression of oneness in you life. These sense-messages easily give rise to incomplete beliefs that things are un connected, with accompanying thoughts, words, deeds. When you say an infinite number of things exist in the universe, you're recognizing that there are differences between things.
Differentiation is a fundamental characteristic of the universe.
But individual or type difference does not indicate separation from a common root. For practical purposes, we can believe that all of the different things in the universe are interconnected within a single thing, the one universe. If you use the analogy of a family tree, everything sprang from one creative activity. Distinctive difference is as important in the universe as it is in our bodies. If you can carry this awareness of the importance of differentiation and the resultant diversity to other life forms, other physical forms, or other social, ethnic, national, political, and economic forms, then you're on your way to understanding oneness.
