THE KATHA OF SHANI DEV

Shani literally means the “slow-moving-one”. He is the son of Surya and Chhaya. When he was in his mother’s womb, she was engrossed in penance of Shiva in blazing sun and didn’t even care to have food. So, Shani Dev was born with dark skin.

Once when Hanuman was praying to Sri Ram, Shani Dev came to him and asked Hanuman to fight with him. Hanuman Ji tied Shani in his tail and tightened the coil. He, then, moved his tail in all directions. Shani Dev started bleeding and was in immense pain.

To relieve his pain, Hanuman ji gave Shani Dev some oil and sesame seeds. Since then, it has become a practice to worship Shani Dev with oil and sesame seeds.
It not only soothes his pain, but also makes him beneficent towards Ram and Hanuman devotees.

Ravana,once, took all the 9 planets as captive. When Hanuman went in search of Ma Sita, he freed Shani Dev.

Shani Dev then said to Hanuman that the effect of Shani’s inauspiciousness will never affect him in any way. He also promised not to trouble anyone who was a Ram Bhakta.

Shani is also a Devta of justice. He is known to give one the fruits of his deeds in his present life itself. He keeps a faithful account of our previous Karma.
The Shani Mandir at Shingnapur (Maha) is the most famous Shani Mandir. Even to this day, people do’nt lock doors here.
