We do not build some shape from clay or wood or metal and call it Ahura Mazda because, to us, Ahura Mazda is ever glowing eternal light from which emanates bounty and goodness. Zarathushtra also taught that Ahura Mazda regulates the universe through Asha, the law of precision. At the physical level Asha represents the laws in the universe. Scientists try to understand these laws, such as the laws of gravity and electric and magnetic fields. On the psychological level Asha is the powerful force of truth while at the spiritual level Asha is the fusion of order and truth leading us to the path of righteousness.
Righteousness is the universal law that stands for order, evolution, progress and projection.
The Human Mind is the best gift that Ahara Mazda has bestowed upon us. With our Vohu Manoh we can not only think but we can reason and articulate and this is what makes us so unique from all other living species on this planet. We have a mind that can help us differentiate and distinguish between right and wrong, good and evil. Ahura Mazda is in accord with Asha and he wants us to promote this path of asha , ashoi and ashem . According to this law good deeds produce good rewards and evil deeds have bad consequences.
