Death of Jarasandha

Bhima and Jarasandha fought non stop. First it was with maces. Jarasandha said to Bhima You have invited your death by coming to Magadha. Bhima said Death is calling out to you. I have come as death's messenger.
Maces discarded they started wrestling. They started throwing each other around, in the arena.
The sounds they made were loud. Slapping of bodies and their voices were the only sounds that could be heard.
They picked up the maces again, and sparks flew when the maces struck each other. For fourteen days they kept fighting.

The two were tired. Constant fighting without a break and food was getting to them.

Jarasandha soon collapsed on the ground. Taking this as an opportunity, Bhima picked up Jarasandha and swinging his body around, dashed it against the ground. He was surprised to see Jarasandha alive.
Bhima looked at Krishna for help. Krishna said to Bhima, you have forgotten about Jarasandha's birth. To kill him, you will have to tear his body into two.

Bhima taking that as a clue, went back. Pressing one foot of Jarasandha, he ripped the body apart and threw the body pieces away. Jarasandha was dead.

Hearing this, Sahadeva, son of Jarasandha came to Krishna and fell at his feet. Krishna consoled him and announced that he would be the next king of Magadha. All the imprisoned kings were released. Krishna asked the kings to return to their kingdom and show their good will when Yudhistira would be performing the Rajsuya sacrifice.

Krishna along with Bhima and Arjuna then left Magadha in a chariot and reached Indraprastha. They bowed down before Yudhistira and told him all that had happened.

Krishna then set forth for Dwaraka. 

Satyavati's death

One day Vyasa came to Hastinapur and finding his mother alone, spoke to her. He said bad times were going to fall on the dynasty. Dhritarashtra will turn evil and things would not work well.

He asked her to leave the palace and leave for the forests.

Satyavati was worried. She called Ambika and Ambalika and told them what Vyasa had said.

They decided to go with Satyavati. They called Bhishma and told him about their wish.

Soon after, they left with the aged women of Hastinapur accompanying them.

Soon meditating in the forests, they gave up their life.

Death of Pandu

Pandu was living happily with his sons and wives. One day, spring came. The trees around looked wonderful, full of flowers.
Pandu wanted to explore the forest and leaving Kunti and the children, he went inside with Madri.
The king was aroused seeing Madri. Forgetting his curse, he grasped Madri. He tore off her clothes and was about to have sex when he collapsed dead on top of her. The sage's curse was fulfilled. Madri started wailing.

Kunti seeing Pandu not returning, she taking the children along with her went to look for him. She followed the source of Madri's cries and some reached the place where Madri was crying, with dead Pandu on her lap.

Kunti sank on the ground. She told Madri she should have avoided the king, knowing about the curse of the sage.

Madri said she had tried to stop the king but he would not listen.

Kunti asked Madri to look after the children and she said she would end her life. Madri stopped her and said she would be the one who would go with the king. She requested Kunti bring up her two sons along with three of her sons. Saying so, Madri gave up her life.

The sages living nearby came there. With four sages lifting Pandu and Madri, they lit the funeral pyre.

Kunti then accompanied by the sages left for Hastinapur. Bhishma, Vidura, Gandhari, Satyavati, Ambika and Ambalika were there. They greeted the sages and gave them seats.

The sages then told them about Pandu, his sons and his death.

All broke down. Dhritarashtra asked Vidura to arrange for funeral ceremonies for Pandu and Madri. The five sons of Pandu offered meals (Pinda) to Pandu and Madri. Gold and wealth was distributed amongst the poor.
