又智度論云。劫盡燒時一切皆空。眾生福力十方風至。相對相觸能持大水。有一千頭人二千手足。名為韋紐天。是人臍中出千葉金色妙寶蓮華。其光大明如萬日俱照。華中有人結跏趺坐。此人復有無量光明。名梵天王。心生八子。八子生天地人民。是梵天王坐蓮華上。是故諸佛隨世俗故。云寶蓮華上結跏趺坐說六波羅蜜。

Furthermore, the Mahāprajñāpāramitā-śāstra states: When the kalpa ends in conflagration, everything becomes empty. By the power of the merit of sentient beings, winds arise from the ten directions; blowing against and striking one another, they can hold up the great waters. There is a being with a thousand heads and two thousand hands and feet named Viṣṇu. From the navel of this being emerges a thousand-petaled, golden, wonderful jeweled lotus flower, its light blazing brightly like ten thousand suns shining together. Within the flower, there is a being sitting cross-legged; this being also possesses immeasurable radiance and is named King Brahmā. From his mind were born eight sons; the eight sons gave birth to heaven, earth, and people. This King Brahmā sits upon the lotus flower. Therefore, the Buddhas, conforming to worldly convention, are said to sit cross-legged upon a precious lotus flower to preach the six pāramitās.
