"Life is built up by the sacrifice of the individual to the whole. Each cell in the living body must sacrifice itself to the perfection of the whole; when it is otherwise, disease and death enforce the lesson. ...Harmony is the law of life, discord its shadow; whence springs suffering, the teacher, the awakener of consciousness. ...The discovery and right use of the true essence of Being — this is the whole secret of life."
