Hadith and Instant Karma

Prophet Muhammed said:

" There is no better companion on this way than what you do;

Your actions will be your best friend;

Or if you're cruel and selfish,

Your actions will be a poisonous snake that lives on your grave."

I think this explains, along with other things, why people have completely different experiences of seemingly the same trip they have. It is true that on the way it is much easier to experience instant karma. One who travels knows that the energy you emanate attracts a similar energy. Your actions and even thoughts are equally rewarded.
