Why did Ravana imprison all the Navagrahas?
This is one of the very interesting stories from the pages of Hindu Scriptures and you should read this and be amazed to know this rare tale.
Ravana the great devotee of Lord Shiva and renowned Brahmin scholar in the treta yug had imprisoned all the nine navagrahas like Rahu,Ketu,Shukra,Shani,Budh,Brihaspati,Mangal,Chandra and Sun.
Ravan had imprisoned them because at that point of time Ravana’s son Meghnath was about to take birth and Ravana wanted all the 9 navagrahas to be in favourable plantery position so that his new born sun when takes birth becomes invincible and immortal.
But one of the navagrahas changes his position and this changed the fate of his son Meghnath also called Inderjeet later on.He became a true warrior but not an immortal one due to change in position by Lord Shani.
Ravana became furious and imprisoned Lord Shani for years and tortured him immensely since Ravana was very powerful blessed with all knowledge and powera due to strict penance and worship to lord Shiva.
When Ravana kidnapped Sita Mata and Lord Hanuman went to search her in lanka he came across Lord Shani Dev and helped him escape Lanka and on his voyage Lord Shani was thrown with greater force by Lord Hanuman to help him save from the soldiers of Ravana.
Lord Shani was thrown with huge intensity and power that he landed in the hills of Moraina Presently in Madhya Pradesh. He was found unconscious and few sages who found him treated his pain and wounds by applying Mustard Oil-sarso ka tel.
Now you must have understood why mustard oil is offered to Lord Shani dev on Saturdays and other periods of his worship.
Moral :- Gyan and Ahankar can never work together. The most gyanibif becomes ahankari can be calling upon his sarvnash.
