本文分成「緒論、本論、結論」三個標題的撰寫模式，「本論」以五個 小節來探討「華藏世界」的宇宙論與科學觀，分別是： 一、二十重「世界種」的宇宙論與科學觀：介紹二十重「世界種」的構造， 本文以傳統「下狹上廣」的方式做為研究主軸，這種方式也類似「須彌 山」的造形，並配合現代科學家對宇宙「3D 全景」的切片研究圖做比 對，最後以210 個「三千大千世界」為一個「世界種」的起始單位，這 樣約相當於半個銀河系之大。 二、「世界種」構造的星系觀：《華嚴經》上提到「世界種」有二十種形狀， 本節試圖以當今宇宙天文圖片來詮譯這二十種的「世界種」造形。 三、「世界海」的宇宙論與科學觀：「世界海」是由111 個「世界種」所構成， 約為60 個銀河系之大。 四、「華藏莊嚴世界海」的宇宙論與科學觀：本節探討「華藏莊嚴世界海」 如「帝網天珠」的構造，進而串連成一個「世界網」的圖像，並以現代 天文家所製的宇宙影像做佐證。 五、圍繞「華藏莊嚴世界海」之十個世界海的宇宙論與科學觀：《華嚴經》 上名為「十方世界海」的造形是以「華藏莊嚴世界海」加上圍繞其旁的十個世界海，共有十一個「世界海」，這樣可推出約有660 個「銀河系」 (目前科學所發現宇宙最少有1000 億個「銀河系」)。 「結論」中說《華嚴經》指出有「一億世界海」(約60 億銀河系)的塵數 諸菩薩眾來此集會，聽佛宣講「華藏莊嚴世界」，若這「一億世界海」是屬 於「可觀測」的星系來說，它仍然在現代天文學家所討論的可見0.5%星系 內而已。宇宙的浩瀚無窮無盡，終需會歸「萬法唯心、色即是空」的「一 真法界」性空境界。

This paper is divided into three parts: “prologue,” “body,” and “conclusion.” The “body,” divided further into five sub-divisions, is devoted to the exploration of the cosmological and scientific worldviews of the “Flower-Treasury Universe.” The key points are as follows: 1. Cosmological and scientific worldviews of “Universal Variety” of twenty layers: This division aims to explicate the “Universal Variety” of twenty layers, based primarily on the traditional analysis in the shape of “funnel,” which is similar to the shape of “Mount Sumeru.” Moreover, this shape is further studied symmetrically and contrastively with the figures of “three dimensional panorama” of the universe made by modern scientists. Finally, the very fundamental unit of a “Universal Variety” as “three thousand billion-world universe (san-qian-daqian-shijie)” is set up and confirmed. This is roughly tantamount to half the amount of the “Milky Ways.” 2. Astrological worldview structured by “Universal Variety”: Through the study of “Avatamsaka Sutra”, we come to know that “Universal Variety” takes twenty forms. This division aims to describe these various forms by citing the cosmological pictures of modern day.3. Cosmological and scientific worldview of “Universal Sea”: “Universal Sea” comprises of 111 “Universal Varieties,” an amount roughly equal to that of 60 “Milky Ways” in total. 4. Cosmological and scientific worldview of “Universal Sea Adorned by Flower-Treasury”: This division is devoted to delineating the components of the “Universal Sea Adorned by Flower-Treasury,” such as “The Jewel Net of Indra.” This is further developed into the image of “Universal Net,” an image already confirmed by the images and pictures drawn or taken by modern astrologists. 5. Cosmological and scientific worldview of the ten “Universal Seas” surrounding the “Universal Sea adorned by Flower-Treasury”: The “Universal Seas of Ten Directions” depicted in the “Avatamsaka Sutra” is based on the “Universal Sea Adorned by Flower-Treasury,” which, along with the ten Universal Seas surrounding it, amounts to eleven in number totally. Six hundred and sixty “Milky Ways” are thus inferred (Modern science has confirmed that there are at least 100 billion “Milky Ways.”). The main point of “conclusion” concerns that, according to “Avatamsaka Sutra”, there are as many bodhisattvas as the mote dusts of “one hundred million Universal Seas” (roughly amounting to six billion Milky Ways) coming and gathering to listen to the Buddha’s sermon on the “Flower-Treasury Universe.” If this “one hundred million Universal Seas” belong to the “observable” constellations, it accounts for merely 0.5% of the constellations observed by modern astrologists. The immeasurable and limitless universe is eventually categorized by “the One True Dharma Realm,” the realm being empty of selfhood.
