One of the most renowned stories associated with Kamalatmika Devi is her role in the cosmic churning of the ocean (Samudra Manthan). According to Hindu mythology, gods and demons churned the cosmic ocean to obtain the nectar of immortality (amrita). During this epic event, Kamalatmika Devi emerged from the depths of the ocean, seated gracefully on a lotus flower. Her divine presence brought forth abundance and prosperity, blessing the world with fertility and wealth.

Another popular tale recounts Kamalatmika Devi's encounter with the demon Banasura. The demon, driven by arrogance and ego, sought to challenge the gods and disrupt cosmic order. In response, Kamalatmika Devi manifested her divine form and engaged in a fierce battle with Banasura, ultimately vanquishing him and restoring harmony to the universe.
