Drawing upon the teachings of the Kegon Sutra, and moving beyond the idea of individual salvation through nenbutsu, Ryônin postulated that since all men are one with the universe, that any and all instances of chanting the nenbutsu earned spiritual benefit for all mankind. He called this the yûzû nenbutsu. He thus traveled the land, seeking converts and collecting signatures of those who would recite the nenbutsu; he is said to have collected roughly 3,800.
