The seventh volume of Devayana contains the last eight Parvas of the Mahabharat. We see how Dhritrashtra, with immense anger coursing through him, crushed Bhima`s iron statue into smithereens. Ashwathama’s anger was manipulated by Kali, Shani and Rudra Maheshwara to destroy the family and allies of the Pandavas as they slept. The forces of good in the world were destroyed, so that the Kaliyuga could commence in full earnest. We see, how certain persons, influenced by hidden forces, acted like puppets.  Ashwathama, after realising the magnitude of his heinous crime, could only repent. The only survivor of the Pandavas was the unborn grandson of Arjun, Parikshit. That occurred only with the help of Lord Krishna and Rishi Vyasa. The great Bhishma, lying on his bed of arrows, while waiting for the right time to leave his body, told Yudhisthir about his duties to bring about peace in the world. He showed him how to overcome his sorrow through administering his kingdom well. He also elucidated in a clear manner the elements of a good administration, the duties of the rulers and the subjects, the standards of good governance, division of wealth among the entire population, and how peace and prosperity could be furthered in the land. After the twin Yajnas of the Pandavas and the Yadavs, the world again becomes peaceful and divine. Then suddenly everything changed. Kali, the leader of the Kaliyuga asked for Rishi Durvasa’s help in the destruction of the Yadavs. Through a simple curse, an unnecessary conflict ensued amongst them. In a short time, all the Yadavs died fighting amongst themselves.

Lord Krishna then decided to leave the world. With his departure, and according to his own wishes, Varuna allowed the glorious island state of Dwarka to be engulfed by monstrous waves and dragged down to the bottom of the sea. Together with incessant and heavy downpour, all signs of the Yadavs disappeared from this world except for the grandson of Lord Krishna, Vajra. The Pandavas also decided voluntarily to leave this world and go walking up the Himalayas to reach heaven. They left behind their little grandson, Parikshit, as the ruler under the tutelage of Rishi Vyasa. With Rishi Vyasa’s help, Parikshit was protected from evil by an armour, created out of mantras. With Shukdev’s guidance, and with the help of Gods, his Kingdom became a very peaceful and happy one. When Shukracharya, the mentor of the Asuras, came to know that the Gods were helping Parikshit to re-establish their suzerainty in the world, he became very angry. With his anger, his power spread all over. It affected the Gods and made them powerless. They became weak and their time for resting started. Men lost their faith in Gods and became consumed with desire, anger, ego, attachment, jealousy and greed. Also, Shukracharya asked Shani to further diseases, old age, and death. Also natural calamities increased in the world. Humanity became increasingly restless and lost their tranquillity. At that time, Arbuda, the Snake King controlled the power of money. Shukracharya also instructed Kali and Shani to make Parikshit weak and destroy him so that Kaliyuga could begin in earnest.
