Do Unto Others
The People of Bamboo Gate Veludvāreyya Sutta (SN 55:7)
“There is the case where a disciple of the noble ones reflects thus: ‘I love life & don’t love death. I love happiness & abhor pain. Now if I—loving life & not loving death, loving happiness & abhorring pain—were to be killed, that would be displeasing & disagreeable to me. And if I were to kill another who loves life & doesn’t love death, who loves happiness & abhors pain, that would be displeasing & disagreeable to the other. What is displeasing & disagreeable to me is displeasing & disagreeable to others. How can I inflict on others what is displeasing & disagreeable to me?’ Reflecting in this way, he himself refrains from taking life, he gets others to refrain from taking life, and he speaks in praise of refraining from taking life. In this way, his bodily behavior is pure in three ways.”
