But accepting everything that happens to us is still action by omission. Omission is just as much interference as action. I don't see how omission will lead to a greater good than action.
I think you are right about that, an action that comes from within you is good. As I see it, there are things beneficial for you or damaging. Love is beneficial for your physical and emotional health, hate is damaging to the liver and everything else.
Like the parable:
“There was a man walking in the forest, and he saw a big bag of rocks. He got the bag and started throwing rocks at the river, one by one just to see them bouncing in the water.
When there was 1 rock left, he started crying incessantly, another man passed by and saw him crying, asking him what is wrong.
The man said he had been throwing rocks at the river, and when there was only one left, he realized he have been throwing gold to the river the whole time.”
We have a given amount of energy to give until we die, like the sun, and virtually everything that is born. You can spend that energy to benefit or damage yourself, and therefore others by loving or by hating.
I am talking omission when your action would be non-beneficial to you or others. I´m talking omission when you think that by hating you would solve anything, you would be wrong.
