Shiva Dhanush was the divine bow of Lord Shiva gifted to King Janaka ancestor devraj.Lord shiva maded this bow with his power to kill tripura asuras,
Tarakasura had three asura sons named Vidyunmali, Tarakaksha and Viryavana (tripurasuras). These three began to perform tapasya. For a hundred years they meditated standing only on one leg. For a thousand more years they lived on air and meditated. They stood on their heads and meditated in this posture for yet another thousand years.
Brahma was pleased at this difficult tapasya. He appeared before them and said, What boon do you want? Make us immortal, answered Tarakasura's sons. I can't make you immortal, replied Brahma. I don't have the power. Ask for something else instead. Very well, then, said Viyunamali, Tarakaksha and Viryavana. Grant us the following: Let three forts be made. The first will be of gold, the second of silver and the third of iron. We will live in these forts for a thousand years. At the end of the thousand years, the forts will become one. This combined fort will be called Tripura. And if anyone can then destroy Tripura with only a single arrow that shall be the death destined for us.
Shiva agreed to destroy Tripura. Vishvakarma was the architect of the gods. Shiva called Vishvakarma and asked him to make a suitable chariot, bow and arrow. The chariot was made entirely out of gold. Brahma himself became the charioteer and the chariot was speedly driven towards Tripura. The gods accompanied Shiva with diverse weapons.
By then a thousand years had passed so that the three forts had become a single Tripura. Shiva installed a divine weapon known as pashupata into his arrow and shot it at Tripura. The arrow burnt up Tripura into ashes in a split second(three cities of the Asuras which were built of gold, silver and iron by Maya).
LORD SHIVA TOLD DEVAS THAT THIS BOW WAS SPECIALLY MADE FOR KILL THE TRIPURAS ONLY SO NO ONE CAN USE THIS BOW AFTER KILLING OF THE TRIPURAS,LORD SHIVA UNTIED THE BOW YARN AND GIVE TO AYODYA KING DEVARAJ.
LORD SHIVA TOLD DEVAS THAT IN FUTURE(TREDA YUGA)LORD VISHNU WILL TAKE INCARNATION AS RAMA,LAKSHMI WILL TAKE INCARNATION AS SITA,IN SITA SWAYAMVAR RAM WILL BROKE THIS BOW AND MARRY SITA
Lord ram prayed for grace of Lord Shiva,then he raised the bow with ease and thrust an arrow. As he bent the bow, it broke
why other princes can't hoist shiva Dhanush but sita,ram easily hoist the shiva Dhanush ?
Do you think the bow can not be taken by others because of its weight? no
This is because of fatigue and impure hearts of princes . The bow may sucking the prana of impure hearts. Sita and ram are not impure.This may be the reason.
