The story that of, how the Moon god ended up in Lord Shiva's hair, goes like this:
Moon god had to get relief from the disease that he got by his own fault. He came to know that the only remedy for his disease is to be in Lord Shiva's hair. So he prayed to Lord and received a great boon of staying on the Lord's head.
I want to know why in all temples, Moon in Lord Shiva's head is always in curve shape (crescent), not as a full moon or some other positions as we see regularly in the sky.
Is there any reason for this? Is there any place or temple that shows Lord Shiva having other moon shapes?
