Dhammapada 19.270
A man is not an elect (Ariya) because he injures living creatures; because he has pity on all living creatures, therefore is a man called Ariya.
271, 272. Not only by discipline and vows, not only by much learning, not by entering into a trance, not by sleeping alone, do I earn the happiness of release which no worldling can know. Bhikshu, be not confident as long as thou hast not attained the extinction of desires.
