The notion is that human beings are born, (as my Guru has explained many times,) with equivalent potential for both contraction and expansion. The ingredients of both darkness and light are equally present in all of us, and then it's up to the individual (or the family, or the society) to decide what will be brought forth - the virtues or the malevolence. The madness of this planet is largely a result of human being's difficulty in coming into virtuous balance with himself. Lunacy (both collective and individual) results.
