James Legge translation
Bhadra-kalpa, ‘the Kalpa of worthies or sages.’ ‘This,’ says Eitel, p. 22, ‘is a designation for a Kalpa of stability, so called because 1000 Buddhas appear in the course of it. Our present period is a Bhadra-kalpa, and four Buddhas have already appeared. It is to last 236 million years, but over 151 millions have already elapsed.’
