Nothing can bring you peace but yourself.
Nothing can bring you peace but the triumph of principles.
Ralph Waldo Emerson
I owed a magnificent day to the Bhagavad Gita. It was the first of books; it was as if an empire spoke to us, nothing small or unworthy, but large, serene, consistent, the voice of an old intelligence which in another age and climate had pondered and thus disposed of the same questions which exercise us.
Ralph Waldo Emerson, Journals (1822–1863)
