Fasting called “Dog Days” lasts from June 23 to 28 (2-7 degrees of Cancer).
The mystery of this post is connected with the knowledge of what is Light and what is Darkness, what is Evil and what is Good. This is the time of overcoming seductions, purification of thoughts, for it is with the purification of thought that liberation from any defilement and evil begins. The hidden meaning of these days is the protection of the elements and elemental spirits from attacks by dark forces.
At the heart of the universe of the Zoroastrians lies the idea of the trinity of good thoughts, good words and good deeds. This chain of creation begins with a good thought, the mystery of which is played during this fast.
