One should learn how to be united with God; and through practice, when it becomes one’s second nature, one attains the goal. Then one perceives the presence of the Lord within and without, and consequently the changing circumstances of the world cannot perturb one anymore. It is not that disturbing elements do not arise, they do; but they come and go away without having any effect.
(p.154-5, Spiritual Treasures, Swami Turiyanandaji’s letter to Swami Prajnananda on 12 June, 1916 from Almora.)
