In the beginning, when Brahma initiated the creation of the universe, the newly created beings sought their purpose from their creator. Brahma explained that he would continue to populate the earth with various life forms and that these initial beings would serve as their protectors. However, a few of these beings harbored ambitions to dominate all creation, and Brahma, in response to their desire for control, cursed them to become rakshasas, or demons.
One such rakshasa, named Heti, married Bhaya, a daughter of Brahma. From their union, a son was born. Rather than raising the child, Heti and Bhaya left him on a mountain to enjoy each other's company undisturbed. The abandoned infant began to cry, and his cries reached the ears of Shiva. Moved by compassion, Shiva intervened, blessing the child with rapid growth into a handsome youth well-versed in all scriptures. This young man, blessed further by Parvati, came to be known as the progenitor of the rakshasas.
As time passed, this progenitor married and fathered three sons: Mali, Sumali, and Malyavan. These three sons, inheriting the rakshasa nature, were ambitious and powerful. They prayed to Brahma for dominion over the worlds. Brahma granted their request, warning that their rule would last only until they were defeated by Vishnu.
Mali, Sumali, and Malyavan established their kingdom in Lanka and began to wreak havoc across the universe. Their tyranny knew no bounds, spreading chaos and fear among gods and mortals alike. However, true to Brahma's prophecy, Vishnu intervened to restore balance. In a fierce battle, Vishnu defeated Malyavan and Sumali, putting an end to their reign of terror.
Following their defeat, Vishnu installed Kubera, the god of wealth and prosperity, as the ruler of Lanka. Kubera's rule brought stability and peace to the kingdom. Under his guidance, Lanka flourished, becoming a place of wealth and harmony. Kubera's ascension marked the end of the rakshasa dominion and the beginning of a new era of prosperity for Lanka.
