The ideal of non-attachment has been preached again and again in the course of the last 3000 years. It is found in Hinduism, the teachings of Buddha, the doctrine of Lao Tsu, in the philosophy of the Greek Stoics. The Gospel of Jesus is essentially one of non-attachment to the things of this world, and of attachment to God. What the Jewish philosopher Spinoza calls "blessedness" is simply the state of non-attachment, just as Spinoza's "human bondage" is the condition of one who identifies himself with his own desires, emotions, and thought processes, or with their objects in the external world.
