覩史多（梵語也。欲界中空居天名也。舊云兜率陀。或云兜術。或云兜駛多。皆梵語訛略不正也。唐云知足或云妙足。凡聖界地章云下天多放逸上天多闇鈍故云知足。一生補處菩薩多作此天王。雖復萬行齊功十度之中而偏修精進。婆沙論及正法念經等說彼天以寶雲為地。下去大海三十二萬瑜繕那。人間四百年為彼天中一晝夜。壽命四千歲。身形長二里）。

Tuṣita (覩史多; a Sanskrit word. The name of the heaven suspended in the void within the Desire Realm. Anciently called doushuotuo (兜率陀), doushu (兜術), or doushituo (兜駛多); these are all corrupt, abbreviated, and incorrect Sanskrit. In the Tang language it is "Contented" or "Wonderfully Contented". The Discourse on the Realms and Grounds of Sages and Ordinary Beings says: "The lower heavens have much heedlessness, while the higher heavens are very dull and slow, hence it is called 'Contented'." Bodhisattvas destined to Buddhahood in one more birth mostly act as the king of this heaven; although they cultivate all ten thousand practices equally, among the ten perfections they specifically cultivate vigor. The *Vibhāṣā* treatise and the *Saddharmasmṛtyupasthāna-sūtra* say that this heaven has ground made of jeweled clouds, situated thirty-two myriad yojanas above the great ocean; four hundred human years make one day and night in that heaven, and their lifespan is four thousand celestial years; their bodies are two li in height).
