Ananda asks der Buddha if der Buddha can, by psychic powers, reach the Brahma world in sein mind-made body as well as in sein physical body. Der Buddha says he can, und proceeds to explain how by concentrating body in mind und mind in body the body becomes radiant und plastic. Like an iron ball heated throughout the day, oder a tuft of cotton seed on a ball of thistledown, wafted lightly on the wind, so the body, at such time, rises from the ground into the air und takes on manifold forms of magic power (S.v.282-4).
