Hello maitreya,

As always, your post is insightful.

It remembered me the three trainings the Buddha recommend: The training in heightened virtue, the training in heightened mind, the training in heightened discernment. (Vajjiputa Sutta: The Vajjian Monk (AN 3.83) )

Also the Buddha gave a whole process to meditate and reflect about any precept. Goes like this for the case of training against harming life:

"Here householders, a noble disciple reflects thus:

I am one who wishes to live, who does not wish to die. I desire happiness and dislike suffering. Since I am one who wishes to live... and dislike suffering, if someone were to take my life, that would not be pleasant and agreeable to me.

Now, if I were to take the life of another -of one who wishes to live, who does not wish to die, who desires happiness and dislikes suffering -that would not be desirable and agreeable to him, too.

What is undesirable and disagreeable to me, is undesirable and disagreeable to others, too.

How can I inflict upon another what is undesirable and disagreeable to me?

Having reflected thus, he himself refrains from harming life, exhorts others to refrain from harming life, and speaks in praise of refraining from harming life.

Thus, his bodily conduct is purified in three respects."

SN 55.7 Veludvareya Sutta: The People of the Bamboo Gate
Seems to me a kind of general formula so to reflect thus.
