114. Srimad Bhagavatha - Srikrishna Slains Aristasura
Aritasura, a demon disguised as bull with a huge body and a large hump, was sent to Vraja by Kamsa in order to kill Srikrishna.
As the demon bull entered Vraja, it began billowing harshly and shaking the earth with its hoofs. To express its anger, it was throwing mud with its horns and discharging dung and urinating in small quantities.
It's thunder like roar feared the cows and pregnant women. Some cattle fled Vraja. The residents of Vraja sought refuge at Srikrishna, their saviour. Srikrishna asked them not to be afraid.
Srikrishna said to the demon, ‘What will you gain by terrorizing the people of Vraja. I am here to crush you”. Slapping His arms, He provoked the demon. He stretched his arms and placed them on a cowherd's shoulder.
Bending down, the bull rushed towards Srikrishna and attacked Him using its horns. Srikrishna quickly seized its horn and pushed it back to a distance of 18 steps.
The bull quickly rose again and rushed towards the Lord. Srikrishna tightly held the horns of the bull and threw it on the ground. He stepped hard on it and wrung it as a drenched cloth. He pulled the horn and used it as a weapon to strike it.
The bull vomited blood, discharged urine, and dung profusely and met its end. Devatas, who witnessed this event, showered flowers on Srihari. The residents of Vraja were relieved of the danger and praised Him. Srikrishna spent around 10 years at Gokula and Brindavan.
Sage Narada Informs Kamsa the Secret Birth of Srikrishna
As Kamsa’s end was nearing, Sage Narada called on him. On giving due respect, Kamsa asked the Sage the purpose of his visit.
The Sage cautioned him and said, “the female child of Devaki and Vasudeva that had escaped death at his hand was indeed the daughter of Yasoda.
The Lord, appearing as Srikrishna, is the son of Devaki, and Balarama is the son of Rohini. All your agents were killed by these kids, and hence, they did not return to you. Vasudeva had placed Balarama and Srikrishna in Vraja under Nanda's care.”
On hearing it, Kamsa was agitated and intended to kill Vasudeva immediately. The Sage stopped him and said the sons of Vasudeva have been ordained to be his death and not Vasudeva.
Kamsa agreed but bound both Vasudeva and Devaki with iron chains. Sage Narada returned to his abode.
