Shiva. It was when the Naranarayanas meditated at Badaryashrama that Daksha’s famous yajna was conducted. Daksha did not invite his son-in-law Shiva and Shiva threw his trident at Daksha. After destroying the yajna, it sped towards Narayana’s chest. Its energy made Narayana’s hair go pale. (munja) Since then he was also known as Munjakesha. Narayana uttered a hunkara and stopped the trident, and it returned to Shiva.

Shiva became angry and started fighting Narayana. Nara sent an arrow to kill Shiva. The arrow became an axe (parashu) but Shiva broke it. It then became Shiva’s weapon. Shiva later gave it to his disciple Bhargavarama as per Mahabharata Shantiparva Chapter 49 verse 33. Shiva was thus named Khandaparashu as per Mahabharata Shantiparva Chapter 343 verses 159-167.
