Sexual desire is blind, and that poses a problem. When you say to yourself, I want to have sex with that person, you are expressing a desire that the intelligence does not direct. On the other hand, when you think, I want to eradicate poverty from the world, that is an intellectually controllable desire. What’s more, sexual gratification represents only an ephemeral satisfaction. As the great Indian sage Nagarjuna said: “When you have an itch, you scratch yourself. But not having an itch at all is better than scratching yourself for a long time.”
