It is one of the basic disciplines for a Zarathustri. If you have ever look at the pictures of Zarathustris from the past, you will recognize them simply because they were wearing cap or turban covering their head. If you read the description of Parsees from the past and those who first landed in Sanjan, it is emphatically described that whether a child, female or male they all had their head covered. It is unfortunate that our own community people laugh on us for wearing cap, which is the foundation of all our religion practices. However, such reactions are seldom seen when a Zarathustri will observe a Muslim or Jew demonstrating their practice of covering head during and out of their prayer area.
Some people feel embarrass to wear in public whereas some remove it to protect their hairstyle.
My dear Zarathustris, wearing cap is not imposed upon us but it is a remedy to protect oneself from destructive thought process that will ultimately influence our Urvaan's progression. In short, our existence in this world depends on how we contribute to our Urvaan by following His prescribed Path and leading a good life. As a result, it tends to flee away from the center of light of Staota Yasna. The steady warm temperature in that area fortifies the most exalted part of the head - the part that endows an individual with the power of creative thought. He possessed Gathic powers including 5 divine senses to visualize and absorb Ahu's power and HIS design of various creations.
