The object of man's worship, whatever it be, will naturally be his standard of perfection. He clothes it with every attribute, belonging, in his view, to a perfect character; and this character he himself endeavors to attain.
Practice means to perform, over and over again in the face of all obstacles, some act of vision, of faith, of desire. Practice is a means of inviting the perfection desired.
A principle is the expression of perfection, and as imperfect beings like us cannot practise perfection, we devise every moment limits of its compromise in practice.
