The entire world is a reflection of one's self. There are no boundaries or limitations in this world that you yourself haven't created. If you want to fly, you can fly just mould the world into your desired entity. The world is but a fragment of your mind and everything from day to day conversations to extraordinary new discoveries are only valuable because you choose to give them value. What I'm trying to say is that the world is just something manifested and percieved by your mind. How do you know that people are the way you think they are? Do you judge them by some universal rules/principles that others use as well. Well, you choose to assimilate those rules into your world perception thus proving all I just said.
