How can God exist if the tsunami killed people who were praying to God?

Swami replied:- People pray to God for their selfish benefits and such prayers are not real worship. If one loves God only in order to satisfy some need of his, it is the worst kind of worship. Apply the same logic to your children. You love your child without any expectation. When you can have such selfless love for your temporary blood bonds of this birth, why can you not have the same love for God, who is related to you by the only permanent bond in this world for the past millions of births? The sea with its millions of waves, warns people not to kill poor aquatic creatures like fish for the sake of food. God has created a lot of vegetable food, which is even better for our health according to modern science. The sea represents the Lord. When humans go against the God’s Law, and refuse to improve, He is forced to punish the sinners and bring them to justice. Natural calamities such as tsunamis are examples of God’s punishment. Goddess Earth (God in the form of the earth) kills the sinners through earthquakes since these sinners kill innocent creatures on the earth. A tsunami is the result of the combined anger of the Father Sea and Mother Earth. Innocent creatures that are slaughtered en masse have no advocate. They cannot even protest or file a criminal case in our courts. Luckily such formalities are not necessary for God’s all-pervading court. You only see the punishment and not the sin. The sin committed earlier is the cause of the punishment. Just as you sympathize with the human beings affected in other countries, since all human beings are one, you should broaden your mind further and feel that all living beings are one. Then you will be able to sympathize with every living being. Natural calamities will then disappear.
