12. The Bhagavad Gita

Thus we see how each stage of development must fulfill its own dharma. What is considered good at one stage must be avoided as evil at the other stage. Good and evil have their place in the eternal world order; in it they lose the meaning that we attach to them. They are necessary because they are the poles of development, they have emerged from a single origin. Good and evil, action and reaction, condition and complement each other like sleep and waking, like rest and activity, like light and shadow, like brightness and darkness, and they belong to each other like spirit and matter. It is Atma as purest light, the original source of all being, and Aima as its mirror image, darkest point and germinal power in the densest matter, which gives the impetus for the development and refinement of matter in the eternal change of form structures, until the contrariness has risen to the light source of the spirit and reunites with its starting point in Nirvana. From the original unity of world harmony, the eternal reason of all things, being, contrast breaks away – the eternal becoming of matter, which develops out of itself and upwards in countless changing forms to fulfillment, in order to merge from the diversity of appearances, the many, back into a unity, enriched with the countless experiences of the separate units. With Nirvana, the circle closes: the beginning and return to the eternal original spirit.
