To be in tune with nature is to explore every possibility to be a source of joy to all creations following the fundamental principle observable in the workings of nature viz.it is better to give than to receive.
A true Zoroastrian should observe temperance or moderation in his dealings with nature,never to over-exploit the bounties of nature as that would seriously disturb ecological balance to the detriment of mankind.
A true Zoroastrian should regard this world as a battlefield and himself as a soldier under the chieftainship of Ahura Mazda to do battle against the forces of Darkness and Wrong.
A true Zoroastrian should perform actions in accordance with the will of Ahura Mazda,that is virtuous deeds completely devoid of egoism dedicating them to the supreme God.
The true Zoroastrian way of life consists in spreading happiness all around - happiness unto him through whom happiness unto anyone whomsoever.(Yasna 43-1)
Avestic Hoama and Vedic Soma is the name of a plant known to the ancient iranians and the vedic Aryans from ancient times.
The man who identified the Haoma plant was a holy sage named also Haoma who was well advanced in matters spiritual and who got the Iranians acquainted with the excellent qualities of the plant.
The Hoama plant is advantageous both for the body and the soul,because all other intoxicating drinks lead to anger,but the drink prepared from Haoma plant is joy-giving and leads to holiness,and it renders the mind of the poor exalted.Today in Yazashne ceremony juice is extracted from Haoma twigs.
They were 1) Haoma Zaairi or the green Haoma, ii) Haoma fraashmi or the refreshing Haoma and iii) Haoma duraosha or the death-averter Haoma.
In Zoroastrian terminology the phenomenon of death is spoken of as the seperation of consciousness from the physical body (Vendidad 9-43)
According to the Zoroastrian belief a man's soul after death remains within the precincts of this world for three nights, under the protection of angel Srosh,the soul's guide (dastagire ravaan) and the soul of a holy man is happy and joyful because of his good conduct in the material world,whereas quite opposite is the case of soul of a wicked man.
On the dawn of the fourth day after death the soul of the holy man meets face to face with his own conduct called Daena in the Avesta,in the form of a very beautiful maiden with a very fragrant wind blowing,and the maiden leading the soul across the Bridge of Selection; to the best existence,whereas quite opposite is the case of the soul of a wicked man(Fragmentess of Haadskht Nask,chs II and III)
It is not a bridge built of any material like iron,wood or stone,but it is the name of a place where selection for the soul is made, whether it has to proceed to heaven or to be dragged down to hell.
If a man's good deeds in the material world outnumber his evil deeds his soul is entitled to Behest which is of four different grades (i) Humata(star station) (ii)Hukta(moon station) (iii) Hvarshta(sun station) and (iv) Anagra raochaao (endless light) or garodemaan (house of songs) (fragments of Haadokht Nask chs II and III)
If a man's evil deeds in the material world outnumber his good deeds his soul is doomed for Dozakh which is also of four different grades (i)Dushmata (ii)Duzukhta (iii) Duzvarshta and (iv)Anagra temah (endless darkness)
When a man's good and evil deeds are equal his soul is entitled to a place called Hamistagaan where there is neither happiness nor much sorrow.
