"A man should wander about treating all creatures as he himself would be treated."
Agamas Sutrakritanga 1.11.33
"All the living beings wish to live and not to die; that is why unattached saints prohibit the killing of living beings."
Suman Suttam, verse 148
"Nothing which breathes, which exists, which lives, or which has essence or potential of life, should be destroyed or ruled over, or subjugated, or harmed, or denied of its essence or potential. In support of this Truth, I ask you a question -Is sorrow or pain desirable to you ? If you say yes it is;, it would be a lie. If you say, No, It is not; you will be expressing the truth. Just as sorrow or pain is not desirable to you, so it is to all which breath, exist, live or have any essence of life. To you and all, it is undesirable, and painful, and repugnant."
