Ok, the title is a bit on the hyperbolic side. For many years I have been brushing or blowing mosquitoes off of me, saving earthworms drying out after a rain, rescuing frogs from window wells, etc. Fairly regularly I have to deal with wasps while working outside, I've come to a compromise position of knocking their nests down with a long pole rather than blasting them with wasp spray. This past week there was a large nest a few feet away from where I was working such that I could just let it be, but a big bully wasp was having none of it and was out for blood (maybe he heard what I did to the bee's nunnery). Anyway he was preventing me from doing what I needed to do and it would have been fairly time consuming to come back later, so for the first time in a long time I very intentionally killed something. I'm not burdened by guilt or anything (wasps and I are not on speaking terms) but the effect taking such an action immediately had on my mind was noticeable and was a good demonstration of the important effect practicing the precepts has for ones practice.
