Parashurama

Parashurama (), also referred to as Rama Jamadagnya, Rama Bhargava and Virarama, is the sixth avatar among the Dashavatara of the preserver god Vishnu in Hinduism. Hindu tradition holds him to be the destroyer of the evil on Earth. According to legends, Shiva advised him to go and liberate the Mother Earth from felons, ill-behaved men, extremists, demons and those blind with pride. He is described as one amongst the ''Chiranjivis'' (Immortals), who will appear at the end of the ''Kali Yuga'' to be the guru of Vishnu's tenth and last incarnation, Kalki.

Born to Jamadagni and Renuka, the Brahmin Parashurama was foretold to appear at a time when overwhelming evil prevailed on the earth. The Kshatriya class, with weapons and power, had begun to abuse their power, take what belonged to others by force and tyrannise people. He corrected the cosmic equilibrium by destroying these Kshatriyas twenty-one times (leaving some lineages). He is married to Dharani, an incarnation of Lakshmi, the wife of Vishnu.

In the epic ''Ramayana'', he arrives after Sita Swayamvara, upon hearing the loud noise when Rama uplifts and breaks the divine bow Pinaka. He later deduces that Rama is Vishnu himself, he himself asked Rama to destroy the fruits of his austerities. In the Mahabharata, Parashurama, the formidable warrior-sage and sixth avatar of Vishnu, is renowned for his unparalleled martial prowess. While the epic does not explicitly state the exact number of days Parashurama would have taken to conclude the Kurukshetra war, his legendary feats suggest that he could have ended it swiftly.

Given these accounts, it's widely believed in various retellings and interpretations of the Mahabharata that Parashurama possessed the capability to end the Kurukshetra war in a single day. However, he chose not to participate in the battle, adhering to his vow of renunciation and neutrality.

Therefore, while the Mahabharata doesn't provide a specific duration, Parashurama's legendary martial abilities imply that he could have concluded the Kurukshetra war in just one day.

In the epic ''Mahabharata'' he was the guru of Bhisma, Drona, Rukmi and Karna.

Parashurama is said to carry various traits including courage, aggression, and warfare along with serenity, patience and prudence. He was known to show his benevolence to Brahmins, children, women, old men and other weaker sections of the society. Provided by Wikipedia
