My mind has continued to play with these ideas ever since. And I continue to live a normal life. Every person must come to terms with the facts that the world is not safe and never has been. Contemplating the end of life on this planet is no different than contemplating the end of life in one's city in case of natural disaster. The cause does not change the results. Mortality is the same. The Cuban Missile Crisis was just a new name for the same questions that Arjuna asked Krishna in the Bhagavad Gita. When Arjuna did not want to go to war "I don't want to go to war. I don't want to kill my cousins," Krishna answered, "What? You think if you don't kill them today, they'll live forever? You are a warrior. Is there something wrong with your profession?"
My volunteer big sister says she thinks reincarnation is likely because nature recycles everything else. That is one answer to the question. But I think the real answer is that we don't know and my true task is to be content with that. I don't know how anything I attempt will come out. So why should continued life on this planet be any different? There is nothing wrong with being a warrior.
