God hanuman is the incarnation of lord shiva and the great devotee of lord Rama. He helped to remain in the war with Ravan. Mace is the weapon of this god. The other name of Hanumanji is Mahaveer, pavan suta, Bajrangbali, kesharinandan.
In the story of lord hanuman and shani dev, god surya is the father of Shanidev. Surya dev is also the guru of Mahaveer. After the completion, surya dev said to pavan suta, “you have become adept in all forms of wisdom and weapons, now to go to your mother anjana” but Bajrangbali requested to surya dev “give me an opportunity to repay for your tutelage” surya dev said to Mahaveer,” my son Shani is the cause of my sorrow, go and bring that wayward son of mine back to me”. In this situation, Mahaveer went to shanilok, many planets tried to stop him but they were unable.
When Shani dev saw pavansuta he asked to him, “who are you? Why are you come here? Do you not fear with die?” Mahaveer replied that “I am hanuman and Lord Shani you have all power and virtues, but your greatest drawback is disobeying your father. It is not good and it is the greatest sin, so come with me I will take you back.” Hearing all this Shani became angry and said you don’t know my power so thing is that you go back immediately otherwise I will burn you” Bajrangbali replied,” I have to take back to you”. Then Shani dev have anger on Bajrangbali but Shani dev could not burn him so, he sat on his head. They were inside a room. Lord Pavansuta immediately increased his size. When the he have pain then he requested to god Mahaveer to release him then hanuman became free to him and promised to hanuman,” anyone will worship you on Saturday.” After that lord hanuman and shani dev went to surya dev. Shanidev became happy to see them.
