I'm fond of meditation. I just dispute the idea that in a world full of injustices, that meditation is the path to happiness. We need a bunch of extreme anger and indignation to change the world.
Ideally, meditation would spur you on to action; that's the direct aim of engaged Buddhism [1]. But more broadly, many Buddhist schools aim to encourage a direct feeling of love for all sentient beings, which if combined with the philosophy of something like effective altruism [2] (instead of Woo), could contribute to effecting meaningful systemic change.
Also -- I believe Buddhism does not apply negative connotations to 'indignation' as opposed to raw anger, i.e. I don't think it is classified as a negative state of mind to be dissolved.
I don't dispute that "extreme anger and indignation" can change the world, but I'm not convinced that it effects change that is long-term good. Anger and indignation often lead to rash decision making, hostility, vengeance, etc. The world isn't really better when we trade injustice against one group for injustice against another, and extreme anger has an unfortunate tendency to do just that.
Neves, I'm not happy that your comment was down-voted. It's a commonly held view, and one I've held myself. It's a good comment because it's honest.
My personal experience is that anger is accompanied by a level of agitation that makes all action dangerous. If you manage to do the right thing, it is by accident. More often than not, you cause more damage. It's true that anger gives you a lot of energy to accomplish a goal; but it's one of life's sad ironies that it also causes you to fixate on a goal which a) might not be a good one, and b) brings with it a set of (bad) trade-offs.
That said, there may be situations where a jolt of any energy, including that from anger, is ultimately a good thing. E.g. a depressed person unable to do anything, who suddenly feels furious and throws a tantrum and runs away. Gonna be tough in the short-term, but if you're stuck in a rut any change can be a good thing.
Anyway, thanks for the comment and I hope you get more upvotes.
Most of the angry indignant men that I know focused their anger into voting for Trump. If that is your idea of changing the world then I think your on the right track. If it is not then maybe meditation is more helpful than you give it credit.
