All major religious traditions carry basically the same message, that is love, compassion and forgiveness the important thing is they should be part of our daily lives.
The universe that we inhabit and our shared perception of it are the results of a common karma. Likewise, the places that we will experience in future rebirths will be the outcome of the karma that we share with the other beings living there. The actions of each of us, human or nonhuman, have contributed to the world in which we live. We all have a common responsibility for our world and are connected with everything in it.
We manage to swallow flesh only because we do not think of the cruel and sinful thing that we do. There are many crimes which are the creation of man himself, the wrongfulness of which is put down to their divergence from habit, custom, or tradition. But cruelty is not of these. It is a fundamental sin, and admits of no argument or nice distinctions. If only we do not allow our heart to grow callous, its protest against cruelty is always clearly heard; and yet we go on perpetrating cruelties easily, merrily, all of us - in fact, anyone who does not join in is dubbed a crank.
I have this tattooed on my left side! I love the saying and it's a perfect description of Karma, don't judge/discriminate and don't do to someone what you wouldn't want done to you.
I am the owner of my actions, heir to my actions, born of my actions, related through my actions, and have my actions as my arbitrator. Whatever I do, for good or for evil, to that I will fall heir.
