人觀小宇宙 Mesocosm (the human world)
微觀微宇宙 Microcosm (the subatomic world,especially mvcosmos)
The “大、小宇宙”are generally translated as marcrocosm and microcosm, but the Chinese microcosm usually means "human being". Considering that mv microvita is the basis of microcosm, “微宇宙” is designated as microcosm, and meso, which is between marco and micro, is designated as humanistic microcosm(人觀小宇宙).
This translation is in line with the Trigrams Yao(三爻)of the heaven,humankind and the earth (天人地consciousness spirituality, mind and heart, and material body).Humankind habitating between heaven and earth is a spirit, mind, and body life led by the mind.
