I've decided I'm done with beliefs. I need hard evidence or unquestionable logic in order to determine whether anything in Buddhism is true or not.
Karma and reincarnation... Can't confirm their existence. Also, you could argue that these two beliefs were adapted from earlier religions in India.
Therefore, the argument for the existence of karma and reincarnation, in my opinion, has an equal amount of weight as the belief in God and heaven. Or the flying spaghetti monster.
Then, on the other hand, there are parts of Buddhism that can be reasonably verified.
Impermanence and emptiness can be verified as true.
And both can lay the logical basis for compassion.
How can impermanence be verified?
You seen old man walking down the street and you know that will be you one day. All things are impermanent, even you.
How can emptiness be verified?
I prefer the term interbeing to emptiness.
You look at a tree and see it is made up of sunshine, water from the clouds, soil from the earth. Take any one of these away and you don't have a tree. A tree is made of non tree elements.
You are made up of non person elements too.
Thus we can reasonably come to the logical conclusion that emptiness is true.
