Within You is the Power [EPUB ebook] 

You are the architect of your own life: it is yours to make or to mar. By the power of thoughts, you are building; are you building aright?
The power of thought, as Emerson says, is a spiritual power. It is the greatest power that man has at his disposal. The world today is in its present state simply as a result of mankind’s collective thinking; each nation is in its present state of either peace and prosperity, or poverty, murder and anarchy, simply as a result of its thinking as a nation; and each individual is what he is, and his life is what it is, and his circumstances are what they are, simply as results of his thoughts.
