Srila Prabhupada made it clear that often there are no ready, pat explanations for many of life’s ambiguities. For example, in “Laws of Nature: An Infallible Justice,” he writes, “Why do we find so many different personalities? If human beings are nothing but combinations of mucus, bile, and air, why are they not identical? One man is born a millionaire; another is unable to have two full meals a day, despite struggling very hard. Why this difference? Because of the law of karma, action and reaction. One who understands this mystery is in knowledge.”
