Revākhaṇḍa ascribed to the Vāyupurāṇa (RKV) 226.16

226.16

tīrthānyanusaranmaunī trisnāyī saṃsmarañchivam /
revārṇavasamāyoge snātvā sampūjya śaṅkaram /
kālenālpena rājarṣe brahmāpyamalatāṃ gataḥ //

Observing silence, bathing thrice daily, following the pilgrimage places and remembering Śiva, / having bathed at the confluence of the Revā and the ocean and worshiped Śaṅkara, / in a short time, O royal sage, even Brahmā attained stainlessness.
