We are meant to pursue spirituality in our physical world.  The rewards for this are different for each of us, so yours can only be internalized within you.  As you have no concrete evidence of what will be, you cannot explain the rewards coming to another any more than you can explain colors to a blind person or sounds to someone who is deaf.  But keep pursuing, as your rewards will certainly come to you. 

Do you feel as if there is too much pressure on you these days?  Welcome it.  You are like coal.  Handling a lot of pressure will turn you into a diamond.
