John Polkinghorne, a physicist and the 2002 winner of the $1-million Templeton prize, the equivalent of the Noble Prize in religion, mentioned during his award ceremony that "in physical science people are struck by the order and fruitfulness of the world. We live in a world that is rationally beautiful and does indeed look as though it is shot through with signs of mind. So it's quiet natural to ask whether this might not be due to the fact that there is a "capital M", a mind behind it all. Creation is not just some performance of a fixed score that God wrote in eternity. It is a sort of an unfolding process. Theologically, you understand an evolving world as a Creation that is endowed by its creator with fruitful potential but is then allowed to make itself."
The world has a cost, said John. "The very process that turned a world of bacteria into a world of human beings will also allow other cells to mutate and become malignant. Cancer in the world is an anguishing fact, but it is not that if God had been more careful or a bit more compassionate, it could have easily been eliminated. It is the cost of creation making itself." He added that "the fields of science and religion are not rivals; they are complementary to each other. Science asks how things happen and religion asks the deeper question: wheteher there is any meaning and purpose behind it".
Zarathushtra taught that Ahura Mazda designed intellect and conscience and vouchsafed every human being with these potentialities so that we could think and discern what is good and bad for mankind and rationally choose our own path in life. The human mind is the best gift that has been bestowed on us and it represents the loving aspect of Ahura Mazda. By employing our mind and applying our vitalizing energy we can be creative, constructive, progressive and promote Asha (Eternal Truth) which represents not only law and social order but also scientific, philosophical and spiritual truth. Thus, we can realize ASHA through good thinking and by making the right choices in this world.
The principal and cardinal virtue for the followers of Zarathushtra is to adhere to the Zoroastrian creed of Humata, Hukhta and Havarastra (Good Thoughts, Good Words and Good Deeds). Good thoughts can generate good words which in turn lead to good deeds. By employing Kharatu (intellect) and Chisti (comprehension) we can promote what is good, right, virtuous and beneficient and oppose what is bad, wrong, evil and harmful. Every good thought, word and deed can further the triumph of Asha over falsehood.
AVESTA, the Zoroastrian Scriptures, conveys the idea of the immortality of the soul i.e. a life after death and this is a very original concept of Zoroastrianism. Closely connected with this idea is the belief in heaven and hell. Another original doctrine is the coming of a Saoshyant (Saviour) at the end of time to purge evil from this universe.
The "Concise Encyclopedia of Living Faiths" edited by R.C. Zaehner, mentions that the importance of Zoroastrianism does not depend on the number of those who profess it but rather on the influence it has exercised on other major religions of the world. The great fame that Zarathushtra enjoyed with the ancient Greeks, who were so proud of their own learning and wisdom, is sufficient proof of the pre-eminent position Zarathushtra has occupied in the history of world religions.
