Question asked by a devotee: After death someone becomes spirit, some go to heaven and some attain God. What is the secret of this diversity?
Answer by Swamiji: This is the judgment of God. In this world, God has given every soul the free will to perform the actions it chooses. We are all tiny parts of God, and we possess the independence to act as we wish. God never forces His will on us. God's job is just like that of a referee. For example, there is an umpire in a match of cricket. Eleven players come for fielding and two for batting. Along with the players, two umpires also come out on field. They do not play or interfere in the game. They simply stand there, note the actions of the players, and pass decisions. "No ball!" "Lbw!" "Four runs!" "Six runs!" There is no partiality in it. The players are free to play as they wish. The umpires merely pass judgment. Similarly, God too acts as the referee in our lives.
God has given us human body. He has also given us the power of knowledge, so that we may use it to know Him. Now, if someone uses this power of knowledge merely in procuring and eating delicacies to gratify the palate, God will say, "If your only goal was to eat good food, then this human body is not fit for you. For this, a body of a pig will be perfect. I'll give you a body of pig next time, so that you can be completely absorbed in the activity of your choice."
If someone uses the free will to put an end to the body, and commits suicide, then God says, "The pain you were getting was a result of your karmas, and it was your duty to bear it. You have wrongfully put an end to your body. So now you will not get another body for some time. You will become a ghost, who has no gross body."
If someone uses the power of knowledge in pursuing devotion, but is unable to reach the goal in this lifetime, then God will give that soul a human body in next life also, so that it soul may continue its journey to God.
God does three things: He gives us the power to act, He notes our actions, and He gives us the results of our actions. The soul's destination after death is decided by its own actions. This is called the law of karma. We can know its broad principles, but nobody can understand its intricacies, and determine what the exact fruit will be, except God.
