[3] Satyabhama was the daughter of Yadava King Satrajita, the royal treasurer of Dvaraka, who was the owner of the Syamantaka jewel.
Krishna, in order to remove the stain on his reputation, set out with his men in search of the jewel and found it in Jambavan's cave, with his daughter.
They fought each other for 28 days, when Jambavan, whose whole body was terribly weakened from the incisions of Krishna's sword, finally recognized him as Rama and surrendered to him.
[5] Satyabhama bore Krishna 10 sons: Bhanu, Svabhanu, Subhanu, Bhanuman, Prabhanu, Atibhanu, Pratibhanu, Shribhanu, Bruhadbhanu, and Chandrabhanu.
[6][7] Narakasura was a danava tyrant, who captured and governed the city of Pragjyotisha, believed in Assamese tradition to be located in the present-day Assam.
Satya, the wife of the wielder of Sarnga, pierced Naraka with sharp narachas, crescent-shaped arrows and with bhallas.”[9] Mahabharata In the city of Nirmochana that hero slew six thousand Asuras, and cutting into pieces innumerable keen-edged shafts, he slew Mura and hosts of Rakshasas, and then entered that city.
Having slain the Earth's son, Naraka, and also Mura, and having recovered those jewelled ear-rings, the learned Krishna of unparalleled prowess came back, adorned with beauty and undying fame.
KMG Udhyoga Parva chapter 48[10] Harivamsa Seeing the trident, decorated with gold, arriving, Krishna of wonderful deeds, split it in two with a sharp edged arrow (Kshurapra).
Harivamsa, Vishnu Parva chapter 63[11] Srimad Bhagavatam Together with Queen Satyabhama, the Lord mounted His carrier Garuḍa and traveled to the capital of Narakasura's Kingdom.
Naraka threw his sakti lance at Sri Krishna, but the weapon proved ineffective, and the Lord cut the demon's entire army to pieces.
Srimad Bhagavatham 10.59[12] Vishnu Purana Having slain Mum, Hayagriva, and Pancajana, the wise Hari rapidly reached the city of Pragjyotiṣa: there a fierce conflict took place with the troops of Naraka, in which Govinda destroyed thousands of demons; and when Naraka came into the field, showering upon the deity all sorts of weapons, the wielder of the discus, and annihilator of the asura tribe, cut him in two with his celestial missile.
Vishnu Purana, Book 5 chapter 29[13] The legend of the tulabharam is a folktale from Odisha, and is absent in the major scriptures pertaining to Krishna's life.
On one contrived occasion, the sage Narada arrived in Dvaraka, and during the course of a conversation, hinted to Satyabhama that the love that Krishna's favourite wife was Rukmini, and not her.
Narada is said to have persuaded her into accepting this vrata by telling her that Krishna's love for her would increase multifold if she succeeded in the tulabharam.
After donating Krishna to Narada, Satyabhama arranged for a big scale (tula) to be put up, and sent for her huge treasure of gold and jewellery.
While there are different versions in different texts as to why the weighing was arranged, the story of the tulasi leaf placed by Rukmini being worth more in weight than that of Satyabhama's wealth is a common ending.
[14] This episode is also recounted in the Devi Bhagavata Purana: Satyabhama tied down Hari against a tree and presented Him as a gift to Narada; afterwards she, the passionate woman, freed Krishna on paying an equivalent of gold coins.
