For fear of causing terror to living beings, Mahamati, let the Bodhisattva who is disciplining himself to attain compassion, refrain from eating flesh.
Can you imagine if you really let it in that you are not a problem to be solved in any way? Imagine you knew that anything that would tell you otherwise is just a movement of thought in the mind that says "Whatever is, isn't the way it is supposed to be." So the biggest act of compassion starts within. And when the self is no longer seen as a problem, this is called "the peace that passes all understanding."
Apart from selfish reasons, such as fear of punishments, fear of blame, of dishonour, etc, there remains only two motives that can stop (or prevent, "empâecher", Fr.) men from acting badly; the natural sense of commiseration (or "sympathy", - "commisération", Fr.) for one's fellow men - compassion, and the influence of education, by association of ideas ("par l'association d'idées", Fr.) - habit.
As human beings we each have a responsibility to care for humanity. Expressing concern for others brings inner strength and deep satisfaction. As social animals, human beings need friendship, but friendship doesn't come from wealth and power, but from showing compassion and concern for others.
Unfortunately, love and compassion have been omitted from too many spheres of social interaction for too long. Usually confined to family and home, their practice in public life is considered impractical, even naive. This is tragic.
