James Legge translation
(4) “The rishi,” says Eitel, “is a man whose bodily frame has undergone a certain transformation by dint of meditation and ascetism, so that he is, for an indefinite period, exempt from decrepitude, age, and death. As this period is believed to extend far beyond the usual duration of human life, such persons are called, and popularly believed to be, immortals.” Rishis are divided into various classes; and rishi-ism is spoken of as a seventh part of transrotation, and rishis are referred to as the seventh class of sentient beings. Taoism, as well as Buddhism, has its Seen jin.
