If we are to be free in the Spirit, if we are to be subject only to the supreme Truth, we must discard the idea that our mental or moral laws are binding on the Infinite or that there can be anything sacrosanct, absolute or eternal even in the highest of our existing standards of conduct. To form higher and higher temporary standards as long as they are needed is to serve the Divine in his world march; to erect rigidly an absolute standard is to attempt the erection of a barrier against the eternal waters in their outflow. Once the nature-bound soul realises this truth, it is delivered from the duality of good and evil. For good is all that helps the individual and the world towards their divine fullness, and evil is all that retards or breaks up that increasing perfection. But since the perfection is progressive, evolutive in Time, good and evil are also shifting quantities and change from time to time their meaning and value. This thing which is evil now and in its present shape must be abandoned was once helpful and necessary to the general and individual progress. That other thing which we now regard as evil may well become in another form and arrangement an element in some future perfection. And on the spiritual level we transcend even this distinction, for we discover the purpose and divine utility of all these things that we call good and evil. Then we have to reject the falsehood in them and all that is distorted, ignorant and obscure in that which is called good no less than in that which is called evil. For we have then to accept only the true and the divine, but to make no other distinction in the eternal processes.
