in this episode satyavati invites Bhagavan Vyasa to bless the wives of Vichitra veeryan - Ambika & Ambalika with children. Satyavati also reveals a secret to Bhishma which she has kept to herself so far.

Before she got married to Chandanu maharaj she was blessed with a son by Paarashara Rishi and his name was Krishna Dwaipayana .

he had promised to come when I think of him in times of need. this Krishna Dwaipayana is none other than Maharishi Vyasa.

She instructed Ambika Ambalika to please the rishi by their humility and get blessed with sons.

but fate has other plans. Ambika closed her eyes when Vyasa looked at her as his Roopam was too terrible to look at. since she closed her eyes she was blessed with a son who would be blind. he is Dhritarashtra

and when Ambalika was asked to go to him she shivered with fear and her face got whitened. she was blessed with a son who would be born pale in complexion. he is Pandu.

then when asked to go again Ambika sent her maid in place of herself. That maid served Vyasa with utmost devotion that he blessed her with a great warrior who would be righteous in his character. he is Vidhura.

what happens later let's see in the next episode. hariom. this is Rajee patti telling you Mahabharatam.
