Use Buddhism on self:

Use Buddhism on yourself and not on others.
Do not use the theroy on Karma on others and say, if they do so and so things their Karma will get back at them.
NO, don't do that.
If you are a truly good Buddhism you will say so and so did such things and i pray for them and share merits with them so their Karma will not be harsh on them.

Better still, use Karma on yourself and accept everything good and bad including your own parents
as a gift of your Karma.
If the Karma was not good practice practice practice and improve on your future Karma.
That's what Buddhism is for.
That's how i see it and that's what i practice.

Follow me if you like.
If you don't
It's your free will and your free choice, and it's your Karma, and i will pray for you.
