But at some point, animal sacrifice was apparently substituted for human sacrifice in cosmic renewal ceremonies, as well as in other kinds of sacrifice, and so there would seem to be precedent for considered changes in this kind of ritual.
We are not, then, looking for "an excuse to stop performing the sacrifice" but rather a theologically valid way to transform the sacrifice while maintaining its focus and impact, as was done in the alleged transition from human to animal sacrifice.
Don’t feel like something’s being taken away from you.
Instead, know that you have a priority, know what you want in life, are working to get it, and are willing to give up comfort and stuff that gives you instant gratification in order to achieve it. What do you give in order to get more of something else?
Do you invest time, sleep, effort and energy, or give up some of the stuff you’re used to and enjoy doing?
One of the primary functions of sacrifice is the renewal of the cosmos.
In our culture, we regularly celebrate people who become rich by doing exceptional things.
But the nature of those “exceptional things” often requires extremely high opportunity costs.
We also know from a Welsh medieval medical text, and from Irish tradition, that the body is related to the cosmos in Celtic thought.
The eyes may be the stars, sun be the face, breath be the wind, stone as bones, water as blood, soil as flesh, etc.
