One evening Hanuman was meditating before sunset, on the sea shore. At that instance, the son of the Sun, Sani (Saturn), thought that he was so powerful and that every human, god and demon was afraid of him. Sani with his ego came to the seashore where Hanuman was meditating. Sani thought that he will fight with Hanuman and defeat him. Then, Sani, in his egoistic tone, said that he is here and wanted Hanuman to stand up. Hanuman gently asked him to repeat what he just said and asked the particulars of why he was there and why he was bothering him. Sani arrogantly replied that he is the son of the most brilliant Surya and is super strong, called by the name Sani, and that all beings in the universe start shivering with fear the moment they hear his name. He said he came to test Hanuman's strength. He also warned that he is coming into Hanuman's zodiac (astrological chart) to influence his future. Hanuman replied with humility that he is an old monkey and that he is meditating and asked him not to disturb him. Sani, with pride, said that he cannot go without conquering him. Then Hanuman said with a humble tone that he doesn't have the ability to fight. Then Sani said in an insulting way that he is a coward and scared to fight with him. Sani started pulling Hanuman's hand. Then Hanuman sarcastically laughed, saying that Sani does not understand when he is trying to give him advice. Hanuman lengthened his tail and wrapped it around Sani's body up to the neck. Sani tried to release himself from the tightened tail of Hanuman. Hanuman meanwhile realized that he needed to perform pradhakshina around the bridge connecting India and Sri Lanka. Then Hanuman started to go around the bridge and hit his tail on the stones of the bridge. Even though Sani tried with all his strength to escape he could not succeed. Hanuman continued for 108 rounds, hitting his tail on the stones of the bridge built by Rama. By these strokes, Sani's body was severely wounded and started bleeding. Then Sani prayed to Hanuman with a panicked voice, pleading with him and telling him he is great. Hanuman was pleased with Sani's prayers and told him he will leave him off if he agrees not to enter the Zodiac of any of Hanumans devotees. With a moaning voice Sani agreed to this condition. Then Hanuman released Sani from his tail. All of this happened on Sani Trayodasi. Sani Trayodasi occurs when the thirteenth day of the lunar month falls on a Saturday (Saturn's day). Sani now changed his tune. He expressed his gratitude to Hanuman, who had freed him when he was hung upside down by the demon Ravana. He asked forgiveness for his misbehavior and arrogance to Hanuman. Since then, to heal his wounds, Sani desires abhishekham (ointment) with sesame seed oil. Therefore, those who perform abhishekham to Sani on Sani Trayodasi have the radiation of Sani cooled down and are blessed by Sani. Sani is thought to have a negative influence. Certainly this is true. But Sani also has a positive influence! When we become arrogant (like Sani, in the story above), then Sani sends negative influences to beat us up , destroy our ego, and give us humility. Two Sani Trayodasis fall in the near future. One is October 31, and one is November 14, when it is wise to perform a special Rudra Abhishekam and prayers to Sani. Regular worship of Sani and Hanuman give great relief from suffering and problems.
