According to Zarathushtra, Ahura Mazda is full of wisdom and has bestowed upon us, human beings, the power to think and reason so that we can discern between good and evil and rationally choose our own path in life. The freedom to choose is the underlying principle of Zarathushtra’s religion and the dualism reflected in the Gathas, the hymns composed by Zarathushtra and incorporated in the Avesta, the religious book of the Zoroastrians, is not cosmic but moral. Of all the living species on earth only humans can articulate and differentiate between right and wrong and employ their mind to be creative, constructive and progressive or unimaginative, destructive and ignorant. Good and evil are confined to the human mind, and thoughts, when translated into words and actions can produce good or bad results. Humans are ultimately responsible for their choices and reap the consequences of their actions. The law of consequences is not intended to punish but to deliver enlightenment and understanding for what is true and right. Evil can be eliminated by making the wrongful become righteous and by changing human minds through knowledge and understanding. According to Zarathushtra: "Happiness comes to those who make others happy". Zoroastrianism is an ethical religion and teaches that mortals can achieve spiritual completeness and make this world a better place for themselves and for others, by fighting evil and following the Zoroastrian creed of Humata, Hukhta and Havarastra (Good Thoughts, Good Words and Good Deeds).
