19. The thoughtless man, even if he can recite a large portion (of the law), but is not a doer of it, has no share in the priesthood, but is like a cowherd counting the cows of others.
20. The follower of the law, even if he can recite only a small portion (of the law), but, having forsaken passion and hatred and foolishness, possesses true knowledge and serenity of mind, he, caring for nothing in this world or that to come, has indeed a share in the priesthood.
DHAMMAPADA, Chapter 1. The Twin Verses
