Many believe the mighty Hanuman to be an avatar of Shiva. But unlike that of Ram, there are no stories about Hanuman finishing his mortal form on earth. Neither no proof for ascending to heaven.People believe that is because Hanuman is still among us.
According to Hindu mythology, Ram and/or Sita (according to some accounts) granted him the boon of immortality to live forever because Hanuman wanted to stay on earth for as long as people worship Ram.
Now this is the interesting fact. Apparently, Hanuman offers a dharshan himself to those who recite a 'secret mantra', which happens to be Kaaltantu Kaarecharanti Enar Marishnu, Nirmukter Kaaletwam Amarishnu. Hanuman only appears to those who fill certain pre-conditions.
1 - The devotee should be aware of own soul's relationship with Hanuman.
2 - Within 980 metres radius from where the mantra is chanted, there can be no other person who does not fulfill criteria.
