How is the mind which functions on knowledge how is the brain which is recording all the time to end, to see the importance of recording and not let it move in any other direction? Very simply: you insult me, you hurt me, by word, gesture, by an actual act; that leaves a mark on the brain which is memory. That memory is knowledge, that knowledge is going to interfere in my meeting you next time obviously.
Violence is not merely killing another. It is violence when we use a sharp word, when we make a gesture to brush away a person, when we obey because there is fear. So violence isn't merely organized butchery in the name of God, in the name of society or country. Violence is much more subtle, much deeper, and we are inquiring into the very depths of violence.
Without love there is no art. When the artist is playing beautifully there is no 'me; there is love and beauty, and this is art. This is skill in action.
There is an efficiency inspired by love which goes far beyond and is much greater than the efficiency of ambition; and without love, which brings an integrated understanding of life, efficiency breeds ruthlessness.
If you lose touch with nature you lose touch with humanity. If there's no relationship with nature then you become a killer; then you kill baby seals, whales, dolphins, and man either for gain, for "sport," for food, or for knowledge. Then nature is frightened of you, withdrawing its beauty. You may take long walks in the woods or camp in lovely places but you are a killer and so lose their friendship. You probably are not related to anything to your wife or your husband.
