妙法蓮華經玄贊 6.193

6.193

其身量者，贍部洲人身量不定，或時高大、或時卑小，然隨自肘三肘半量。餘三洲人亦隨自肘三肘半量，身或高大。四天王天身量如一拘盧舍四分之一。三十三天身量復增一足，一足者一拘盧舍分為四分，一分中半名為一足。帝釋身量半拘盧舍，時分天身量亦半拘盧舍。此上欲天身量，當知漸漸各增一足。梵眾天半踰繕那，梵輔天一踰繕那，大梵天一踰繕那半，少光天二踰繕那。以上諸天各漸倍增，唯除無雲，應知彼天減三踰繕那。無色無形，不說身量。然論復言「色無色天變身萬億，共立毛端空量地界」。《仁王經》列無色界眾。《阿含經》說無色界天淚下如春細雨，佛邊側立皆是化作，隨時大小非業果身。其大地獄中身量不定，若作若增長極重不善業，感身廣大，餘則不爾。其寒地獄、獨一、近邊、傍生、餓鬼亦爾。諸非天身量如三十三天，此說根本非天。若在此洲，身量便小不定。略依要義分別諸趣，餘一切義如理當知。

Regarding bodily size: humans of Jambudvīpa have indeterminate bodily sizes, sometimes tall and large, sometimes short and small, but always measuring three and a half cubits according to their own cubit. Humans of the other three continents likewise measure three and a half cubits according to their own cubits, their bodies being somewhat taller. The bodily size of the devas of the Four Heavenly Kings is one-quarter of a krośa. The bodily size of the Trāyastriṃśa devas increases by one foot—one foot means that when one krośa is divided into four parts, half of one part is called one foot. The bodily size of Śakra is half a krośa, and the bodily size of the Yāma devas is likewise half a krośa. Above this, the bodily size of the desire-realm devas should be known to progressively increase by one foot for each. [In the Form Realm,] the Retinue of Brahmā is half a yojana, the Ministers of Brahmā is one yojana, the Great Brahmā is one and a half yojanas, and Lesser Light is two yojanas. The heavens above these progressively double, except for the Cloudless [Heaven], where it should be known to decrease by three yojanas. The Formless Realm has no form, so bodily size is not spoken of. Yet the treatise also says: "Devas of the Form and Formless Realms manifest hundreds of thousands of kotis of bodies, standing together within the realm of space the size of a hair's tip." The Humane Kings Sūtra lists the assemblies of the Formless Realm. The Āgamas state that the devas of the Formless Realm shed tears like fine spring rain, standing beside the Buddha—these are all apparitionally created, [taking] size according to the occasion, and are not bodies resulting from karmic fruitions. Within the great hells, bodily sizes are indeterminate: if one has committed and reinforced extremely grave unwholesome karma, one receives a vast body; otherwise, it is not so. The cold hells, solitary hells, secondary hells, animals, and hungry ghosts are also like this. Asuras have bodily sizes like those of the Trāyastriṃśa [heavens]—this speaks of fundamental asuras; if they are in this continent, their bodies are smaller and indeterminate. This briefly distinguishes the destinies based on the essential points; all other details should be understood in accordance with the principles.
