July 5th. Living in the spiritual world . . . is just as simple as living in the natural world; and it is the same kind of simplicity. It is the same kind of simplicity for it is the same kind of world--there are not two kinds of worlds. The conditions of life in the one are the conditions of life in the other. And till these conditions are sensibly grasped, as the conditions of all life, it is impossible that the personal effort after the highest life should be other than a blind struggle carried on in fruitless sorrow and humiliation. Natural Law, Environment, p. 257. July 6th. Heredity and Environment are the master-influences of the organic world. These have made all of us what we are. These forces are still ceaselessly playing upon all our lives. And he who truly understands these influences; he who has decided how much to allow to each; he who can regulate new forces as they arise, or adjust them to the old, so directing them as at one moment to make them cooperate, at another to counteract one another, understands the rationale of personal development. Natural Law, Environment, p. 255. July 7th. To seize continuously the opportunity of more and more perfect adjustment to better and higher conditions, to balance some inward evil with some purer influence acting from without, in a word to make our Environment at the same time that it is making us--these are the secrets of a well-ordered and successful life. Natural Law, Environment, p. 256. July 8th. In the spiritual world . . . the subtle influences which form and transform the soul are Heredity and Environment. And here especially, where all is invisible, where much that we feel to be real is yet so ill defined, it becomes of vital practical moment to clarify the atmosphere as far as possible with conceptions borrowed from the natural life. Natural Law, Environment, p. 256. July 9th. What Heredity has to do for us is determined outside ourselves. No man can select his own parents. But every man to some extent can choose his own Environment. His relation to it, however largely determined by Heredity in the first instance, is always open to alteration. And so great is his control over Environment and so radical its influence over him, that he can so direct it as either to undo, modify, perpetuate, or intensify the earlier hereditary influences within certain limits.
