In the 6th Chapter of Śaṅkara Charitam, Shri Ramesh Venkatraman brings to us the story of Śaṅkara's birth and the ensuing events; along with taking forward the story of Maṇḍana Miśhra and Ubhaya Bhārati and how they became householders.
In the form of Maṇḍana Miśhra and Ubhayabhāratī; Brahma and Saraswati descend to join in Śaṅkara's cause.
The time for the descent of Siva as Śaṅkara has arrived.
