LIFE, THE UNIVERSE AND ALL THE STUFF IN IT.I'm a little disconcerted that a government agency would sponsor a blatant appeal to a specific religious belief. You may or may not believe in the concept of karma. Like Christmas symbols, it's possible to water them down for public consumption so that they lose their religious significance and thereby are allowable under the Constitution. I don't see how this is good for either religion or the State. The young people at whom the ad is aimed are often enamored by the Dalai Lama and Eastern religions, so this is not just a figurative use of the concept. I think that the parents of these young people (and Thomas Jefferson) would be right to be outraged by the governmental intrusion supported by their tax dollars.
Karma is the universe's system of checks and balances. Wherein everything you do has a corresponding effect. It's pretty simple really. Do good things, earn some karma points and raise your chances of good things happening for you. Do bad things and the cosmos may just send a swarm of locusts your way. Or open a black hole above your front yard. Or something similarly unpleasant. Maybe. Possibly. Better to keep things straight.
Based upon my experience in first-grade classrooms in recent years, the broader philosophical question is this. To what extent should taxpayer dollars be used to support propagandizing children in a "good" cause? We probably all recall as children participating in fire prevention programs, not skating where the ice is thin, and being kind to one's neighbor. None of these are related to reading, writing and 'rithmetic, but were deemed non-partisan safety or character building issues. Now one sees non-smoking, anti-meat, and environmentalism creeping into the curriculum from kindergarten on. Are we at a tipping point? At what point is the state just doing its job and at what point are they operating as a state propaganda machine, using the power and resources of the state to force a belief upon children. Is there a bright line somewhere?
