An asur named Lavana pleased shiva through penance and obtained his Trisula(Trident), one of the most powerful weapons in entireity of Hindu mythology.
There was another powerful king named Mandhata who conquered whole earth in a single night,
There is nothing impossible of attainment by persons of virtuous behaviour. Mandhatri conquered the whole world in course of only one night,..
And he also vanquished Indra, lord of gods in combat. As well as conquered three worlds due to his might., ie bested gods, demons and humans of his era.
There the foremost of earthly kings, Mandhatri, vanquished Indra, the chief of the celestials.
However the same king along with his entire army was reduced to ashes when he faced Lavana and the latter used the Trisula against him.
Hurled by the illustrious deity, that weapon is competent to rive the entire Earth or dry up the waters of the ocean or annihilate the entire universe.
In days of yore, Yuvanaswa's son, king Mandhatri, that conqueror of the three worlds, possessed of imperial sway and endued with abundant energy, was, with all his troops, destroyed by means of that weapon.
Endued with great might and great energy and resembling Sakra himself in prowess, the king, O Govinda, was slain by the Rakshasa Lavana with the aid of this Sula which he had got from Siva.
