All through their many-thousand-years-old history, Iranians have considered their sacred and ultimate duty to preserve and celebrate the nature, as well as their human habitats in tranquility, freedom and joy. Therefore, many of their beliefs, rituals and festivities have their roots in the nature, getting their inspiration from this source.

The ancient book of "Avesta", that is sacred to Iranians of all religious creeds, is a book dedicated to the praise of the natural entities such as sky, earth, sun, moon, water, wind, clouds, brooks, seas, plants and the animal kingdom. With a worldly outlook, and devoid of any hegemony, Avesta praises all the world's women and the men, "regardless of where they are born," those who "do strive for the realization of the truth, have endeavored in this way, or will do so in the future," those "who sow fruitful plants in gorgeous paradises." The chants of this book are versed in the name of a grand God, Mithra, "who is the guardian of love and promises" and "bestows families with peace, tranquility and happiness"
