妙法蓮華經玄贊 2.232

2.232

"Knower of the World" means that he thoroughly penetrates both the world of sentient beings and the world of the receptacle. Because he awakens to and enters into the world of sentient beings by relying on the knowledge of past lives and of death and rebirth concerning past and future limits, and by relying at all times on the eighty-four thousand variations of conduct, he knows the differences in the mental conduct of sentient beings across the three times; and because he thoroughly comprehends the world of the receptacle, thoroughly understanding the boundless formation and disintegration of the worlds in the ten directions, such as the eastern direction. Furthermore, because he thoroughly knows the intrinsic nature, causes and conditions, gratification, peril, escape, and path of progress regarding all phenomena in all worlds: that is, he knows the intrinsic nature, which is the fruit. 'Causes and conditions' is the cause; this serves as a general phrase, and the remaining four correspond in order to the four truths.
