four meditation heavens ［四禅天］ ( shizenten): Also, four dhyāna heavens. The four heavens that constitute the world of form. They are named ordinally—the first meditation heaven, the second meditation heaven, and so on—in ascending order of altitude and quality. They are further subdivided into eighteen heavens. When, by practicing the four stages of meditation, one frees oneself of the illusions of the world of desire, one can be reborn among these four meditation heavens. The four meditation heavens are also regarded as four levels of consciousness that one can attain by practicing the corresponding meditation. See also four stages of meditation.
