The battle with the Rishikas was very fearful. The battle that took place between them and the son of Pritha (Arjuna) was equal to the between the gods and the Danavas, the immediate cause of which was Taraka (the wife of Brihaspati).
ऋषिकेष्वपि संग्रामो बभूवातिभयंकरः। तारकामयसंकाशः परस्त्वृषिकपार्थयोः॥
