Chandra's children

Bhishma said - Let me tell you about some more customs. There was a king called Chandraketu. He was married to Chandravati, who was the daughter of the Moon. She had been cursed to be born as a human.
Yudhistira asked - Who cursed Chandra's daughter? Why was she born on earth?
Bhishma said -
Chandra used to go to the house of Brihaspati to study. There Chandra fell with love with Tara, the wife of Brihaspati. He ran away with her when Brihaspati was not at home. When Tara became pregnant with Chandra's child, Chandra left her at her house.
When Brihaspati came to know of his, he cursed Chandra to have spots on his body. He also said Chandra would be born as the son of Arjuna.
Hearing this Chandra said I was not in control of myself when I saw Tara. I curse you to be born as a vulture.
Yudhistira asked How did Brihaspati get relieved?
Bhishma said The Guru was born as a vulture and lived in the forest. He got married and soon his wife gave birth to four eggs which hatched to four little birds. This was a happy family.
One day the vulture went to a forest to get food, leaving his wife to look after the children. A hunter spotted the bird and shot it with its arrow. Wounded, the bird managed to drag itself and take shelter in a temple. The hunter entered the temple and tried to catch the bird which was unable to fly but kept hopping around. This happened seven times. The hunter frustrated, killed the bird by shooting another arrow and took the bird along with him.
Having gone around the temple seven times, the bird was relieved of the curse and Brihaspati returned back home. He asked his wife to abort the child and only he would accept her.
Tara was scared and immediately gave birth to a boy and a girl. Tara picked up her children and said the world would know them as her children. Chandra was not sure if the daughter was his and  cursed her to be born on earth. Sure that the son was his, he took the child and named him Budha.
Tara returned with Brihaspati.
The daughter of Chandra was born on earth as Chandravati.

Moon cursed

The sage said to Janmajeya -
The Pandavas returned to their camp. Yudhistira sat on the ground, unable to control his grief.
Vyasa came there. He asked Yudhistira why he was grieving.
Yudhistira said I am very unfortunate. I wanted my kingdom back and because of that the brave Abhimanyu has fallen today. He had told me that he knew how to enter but did not know how to come out. I had told him I would be behind him, but I was unable to proceed because of Jayadratha. He fought bravely and was killed by unfair means.
Vyasa said Stop your grief. You have no control over destiny. Let me tell you about his previous birth. He was the Moon born as Subhadra's son because of a curse. Listen, as I tell you more.
The sage Garga once went to the Moon with his disciples. The Moon was sitting with  Rohini, lost in her love,  when the sage arrived. Chandra forgot to receive the sage.
The sage got angry at being ignored. He cursed the moon to be born as a human.
The Moon said he had not ignored the sage purposefully and begged forgiveness.
The sage said You will born as the son of Subhadra and Arjuna. You will be a brave warrior and at the age of sixteen you will fight a great battle and will die there.

Vyasa said This is Abhimanyu's destiny. You could not have done anything about this.
Yudhistira said I am not sure how I will face Arjuna. What will Krishna say? What will I say to Subhadra? How will I pacify Uttara?

Vyasa said One dies when the time is up, not before that. Krishna will understand and he will make Arjuna understand.

Saying this, Vyasa left.
