From Buddhism’s Sacred Scripture: The Sutra of the Lotus of the Wonderful Dharma, Chapter 3, Part 8 of 8

But if there are those of keep capacities, wise and understanding, of much learning and strong memory, who seek the Buddha way… If you see a son of the Buddha observing the precepts, clean and spotless as a pure bright gem, seeking the Great Vehicle Sutra… If I described all the characteristics of those who seek the Buddha way, I could exhaust a kalpa and never be done. Persons of this type are capable of believing and understanding. Therefore for them you should preach the Lotus Sutra of the Wonderful Dharma.
