This is the central idea of the Gita- to be calm and steadfast in all circumstances, with one's body, mind, and soul centered at His hallowed feet!
Swami VivekanandaSome men, who begin by saying that the world is a hell, often end by saying that it is a heaven when they succeed in the practice of self-control.
Swami VivekanandaIt is too often believed that a person in his progress towards perfection passes from error to truth; that when he passes on from one thought to another, he must necessarily reject the first. But no error can lead to truth. The soul passing through its different stages goes from truth to truth, and each stage is true; it goes from lower truth to higher truth.
Swami Vivekananda
