Early Life and Boons:

From a young age, Meghnath exhibited exceptional skills in archery and sorcery. Impressed by his dedication, Brahma granted him a boon: upon completing a specific yagna (sacrificial ritual) in honor of his native goddess Prathyangira, Meghnath would become invincible in battle. However, this invincibility was conditional; if the yagna were interrupted, he would be vulnerable to defeat.

Role in the Ramayana:

During the war between Rama and Ravana, Meghnath's strategic brilliance and combat skills posed significant challenges to the Vanara army. He notably used the "Nagapashastra" to bind Rama and Lakshmana with serpent nooses, rendering them unconscious. His prowess was such that he was considered more formidable than his father, Ravana.

Demise:

Aware of the conditions tied to Meghnath's invincibility, Lakshmana, with the assistance of Vibhishana, disrupted his yagna. This act stripped Meghnath of his invulnerability, leading to a fierce battle in which Lakshmana ultimately defeated him.
