The physical nature of the perfume is that it evaporates, and disappears. Nothing can prevent the perfume from disappearing. Because it disappears, if you want to find that sensation, that smell again, you have to perfume yourself again. It’s the same thing with food. It's more interesting because you take a spoon and taste something and the actual taste only lasts one or two seconds, no more. But you start again, and you eat again. To start again and again and again and again until you are filled up.
