All that we eat and drink contains a narcotic, even pure water. Therefore, after eating and drinking, a sort of sleep comes upon us. The soul feels a relief. It feels a little detached from the body. The soul takes pleasure in the experience of the senses, in eating and drinking, in every experience. It indulges in this and the more it indulges, the more it becomes bound to this. It cannot be free from the body and the mind. Its real joy is to attain peace by being free from experience. But it has forgotten this.
