"Attachment is the source of all our pleasures now. We are attached to our friends, to our relatives; we are attached to our intellectual and spiritual works; we are attached to external objects, so that we get pleasure from them. What, again, brings misery but this very attachment? We have to detach ourselves to earn joy. If only we had power to detach ourselves at will, there would not be any misery. That man alone will be able to get the best of nature, who, having the power of attaching himself to a thing with all his energy, has also the power to detach himself when he should do so."

- Swami Vivekananda, "Work and Its Secret" (What Brings Success, Jan 4, 1900, Los Angeles, Complete Works: Vol 2)
