The Law of Karma boils down to becoming a vegetarian immediately and at once. If we have not yet become a vegetarian, it means we are not even standing at the portals of the Kingdom of God.
God is not a person. God is the fundamental substratum-consciousness. We are all gods. Everything is God. We only have to realise this and evolve.
We Create Our Own respective Realities There is a No Injustice whatsoever, There is no partial GOD over there.
We are all gods in theory. However, we should become Gods in practice. We should practice God-hood in all of our thoughts, words and deeds.
We are all GODS in potential. However, we should become GODS in practice. We should practice GOD-HOOD in all our moment-to-moment thoughts, time-to-time words and daily on-going deeds.
As long as you don't know you are a GOD... you go out to worship some other GOD. When you understand you are GOD, then there is no temple, there is no church, and there is no worship.
