Skandapurana 16.241

Īśvara said:
There itself one should behold the body of Balabhadra, / where, in the form of Śeṣa, he cast off his own body.

O goddess, he went to the Traisaṃgama sacred ford there by the path to Pātāla / in this Mitravana extending for two gavyūtis.

There, O goddess, his body stands, shaped like a liṅga, endowed with great splendor, / accompanied by Revatī, well-known under the name of Śeṣa.

Where of old, O goddess, the hunter named Jarā achieved perfection— / the slayer of Viṣṇu at Bhallatīrtha—he dissolved into this place.

Ever since then, he has been celebrated as Śeṣa across the whole [world]. / The person who worships him on the thirteenth lunar day of the bright fortnight of Caitra / spends the year in peace, endowed with sons, grandsons, and cattle.

For children there will be no danger from diseases such as smallpox; / no danger ever arises from eruptive diseases such as boils.

The sacrifice that is recalled as the Siddhayajña in this great, perfect sacred field / is exceedingly dear to all the castes and the intermediate classes.

Through animal offerings, floral gifts, and various kinds of oblations, / Śeṣa, the destroyer of all sins, quickly attains satisfaction.

Thus ends the two hundred and forty-first chapter, entitled 'The Description of the Māhātmya of Śeṣa,' in the first [part], the Prabhāsakṣetramāhātmya, of the seventh [section], the Prabhāsakhaṇḍa, in the glorious Skandapurāṇa, a compendium of eighty-one thousand [verses].
