A certain motion becomes understood when it is referred to a force; certain sensations, to matter; certain changes outside, to law; certain changes in thought, to mind; certain order singly, to causation - and joined to time, to law.
Swami VivekanandaOur misery comes, not from work, but by our getting attached to something. Take for instance, money: money is a great thing to have, earn it, says Krishna; struggle hard to get money, but don't get attached to it. So with children, with wife, husband, relatives, fame, everything; you have no need to shun them, only don't get attached. There is only one attachment and that belongs to the Lord, and to none other.
Swami Vivekananda
