"We are all dwellers in two kingdoms, the inner kingdom, the kingdom of the mind and spirit, and the outer kingdom, that of the body and the physical universe about us. In the former, the kingdom of the unseen, lie the silent, subtle forces that are continually determining, and with exact precision, the conditions of the latter."To strike the right balance in life is one of the supreme essentials of all successful living. We must work, for we must have bread. We require other things than bread. They are not only valuable, comfortable, but necessary. It is a dumb, stolid being, however, who does not realize that life consists of more than these. They spell mere existence, not abundance, fullness of life."Ralph Waldo Trine was a philosopher, mystic, teacher, author and early mentors of the New Thought Movement. As an author Trine has far outsold other New Thought authors.
