Zeshta's origin relates to an important event which took place during the churning of great ocean kshirasagra. Devtas and Asuras both desirous of attaining morality were yearning for getting the nectar from Ksirasagara.At the same time they were conscious that this nectar would become available to them only if Lord Siva, who is holder and controller of Ksirasagara, permitted them to churn it.
