New Delhi: If you have noticed, every temple where lord Hanuman resides has an idol of Hanuman ji where he is smeared with dark orange sindoor (vermillion).
If you wonder what it is for, well, there's a story behind it.
Legend has it that Lord Hanuman was once curious about the vermillion that Sita mata had applied on the parting of her hairline. Upon asked by Hanuman about the reason behind applying it, Sita replied to the bhakt of Lord Rama that she applied the sindoor for her husband's long life and to make him happy.
This made Hanunam utterly happy and he dissapeared only to come back with his body covered in sindoor. Each part of his body was covered with this vermillion. Ashtonished, Sita asked to Hanuman the reason behind doing so. Lord hanuman then replied that he did this to make Lord Rama happy and so he could be blessed with a long life.
When Lord Rama heard this, he gave a boon to all his devotees that whoever worshipped Lord Hanuman and applied sindoor on his idol; blessed will be his life and all his wishes will be fulfilled.
