In this passage of the Vishnu Purana, the various incarnations of Vishnu's wife Lakshmi are described:
For in like manner as the lord of the world, the god of gods, Janárddana, descends amongst mankind (in various shapes), so does his coadjutrix Śrí. Thus when Hari was born as a dwarf, the son of Adití, Lakshmí appeared from a lotus (as Padmá, or Kamalá); when he was born as Ráma, of the race of Bhrigu (or Paraśuráma), she was Dharańí; when he was Rághava (Rámachandra), she was Sítá; and when he was Krishńa, she became Rukminí. In the other descents of Vishńu, she is his associate.
I asked about the wife of Vishnu's incarnation Vamana in the dwarf in this question. But now I'm wondering about Vishnu's other incarnation Parashurama. I had always assumed that Parashurama was either a Brahmachari or Sanyasi, but it looks like he was married. My question is, what is the story of Parashurama's wife Dharani? Who is she, and how did Parashurama marry her? At what point during his life did he get married, and what was Dharani doing while Prashurama went around killing the kings of the world?
The only information I can find at first glance is from this Wikipedia article, which mentions a brief incident involving Parashurama and Dharani:
Parashurama once became annoyed with the sun god Surya for making too much heat. The warrior-sage shot several arrows into the sky, terrifying Surya. When Parashurama ran out of arrows and sent his wife Dharani to bring more, the sun god then focused his rays on her, causing her to collapse. Surya then appeared before Parashurama and gave him two inventions that have since been attributed to the avatar, sandals and an umbrella.
In any case, are there any other scriptures which mention Dharani?
