In this world, people are always fighting over property. They want to stake their claims of ownership on both the living and the nonliving. According to the Sri Ishopanishad, these people are like thieves fighting over stolen loot. If we look at the question from the relatively short-term view, we may find it hard to accept that no one is really an owner of anything. But if we adopt the point of view of the Sri Ishopanishad—which sees the universe not in terms of decades, centuries, or even thousands of years, but in terms of many millions of years—then we can understand this point.
Why does a person claim ownership of a thing or of another person? To control it or them. And why does he want to control it? Usually because he wants to be the enjoyer of it.
Unfortunately, a person who is materialistic, greedy, and self-worshiping wants to take the place of God. He sees himself as the center of the universe. He sees everything and everyone—the world, people, his family, animals, plants, the environment—as revolving around him. He sees everything and everyone as meant for his enjoyment. The world is full of such exploitative people, and they cause so many problems.
If a person sees himself as the Supreme Enjoyer, he will automatically live a life of exploitation. He will not respect others or the environment, nor will he care for the well-being of others. He will lead a hedonistic life of unrestricted sense enjoyment, lording over everything and everyone. Although human in form, he will be no more than an animal who lives by the philosophy "might makes right."
History has shown us that our tendency to colonize and exploit other regions has always backfired. This planet can be made a happier, more peaceful place to live in, but the change will have to come from within the hearts of all of us living here.
