So the author hands out leaflets explaining why Engaged Buddhism is ineffective without listening to the real point - to do our best as individuals to help others and to work on the cultivation of our own awareness of truth.
Even if we ran around and were successful at fixing all the problems of the world, if we haven't cultivated joy in our own hearts, we would look around and still feel empty. Even worse, all the problems in the world that we thought were the cause of our unhappiness wouldn't be there as our excuse not to be happy.
Can Engaged Buddhism do better? Of course! Can the "Bureau of Public Secrets" do better? Asolutely! (I'd never heard of them before today, and I've been a bleeding heart liberal all my life! lol) Should Buddhism be exclusively socialy active? No - all human beings have spiritual needs that social activism alone simply will not fill. There needs to be time in my day that I turn off all the noise of what is wrong with the world and recharge my batteries at the very least.
