For me, life is 99 percent a spiritual quest. And it started in childhood with myself and nature, and the universe. And finding truth, finding serenity, finding myself by being immersed and embracing the whole thing that is part of us, that has created us, evolved us, that we are part of. Space flight has allowed me to extend that into unbelievable kinds of realms in which you see a third of the earth, in which you see entire continents, and you see patterns. And you come over the Near East and you see, framed in the space ship window, all of the civilizations, the old civilizations. And you see nature at work, and great, huge lines of volcanoes, from the tip of South America, all the way up through the Aleutians and Alaska.
