In my Buddhist tradition,
Om Mani Padme Hum.
May sentient beings be free from suffering and the causes of it.
May sentient beings never be separated from sorrowless bliss.
I'm not yet able to go full herbivore this life, but I do not take pride in my mouth being the resting place for dead sentient beings. I regret and repent for each bite of meat that I partake in consuming.
