Account of the Birth/Origin of Vyāsa
इति कृत्वा मतिं धीरो व्यासः सत्यवतीसुतः । भागीरथ्यम्भसि स्नात्वा जग्राह नियमं व्रती
iti kṛtvā matiṃ dhīro vyāsaḥ satyavatīsutaḥ | bhāgīrathyambhasi snātvā jagrāha niyamaṃ vratī
Thus, having resolved in his mind, the steadfast sage Vyāsa, son of Satyavatī, bathed in the waters of the Bhāgīrathī (Gaṅgā) and, as a disciplined votary, undertook the prescribed observance (niyama).

Sthala Purana: Vyāsa’s Gaṅgā-bath and adoption of niyama prepares him for Śiva’s grace; the verse foregrounds tīrtha-śuddhi as a precondition for successful upāsanā.
Significance: Snāna in Bhāgīrathī is presented as purification supporting vrata and worship; it functions as sādhana-saṃskāra for approaching Śiva.
It highlights sankalpa (firm inner resolve) joined with outer purification and disciplined observance—showing that steady mind (dhīratā) and niyama prepare the seeker for Shiva-knowledge and liberation (moksha) in a Shaiva framework.
By first taking niyama after sacred bathing, the devotee becomes fit for Saguna Shiva worship—such as Linga-pūjā with mantra and purity—where external rites support inward concentration on Pati (Shiva).
A preparatory practice is implied: sacred bath (snāna), followed by a vow/discipline (vrata-niyama) and mental resolve (sankalpa), which can be paired with japa of Shiva’s mantra (e.g., Om Namaḥ Śivāya) as the observance proceeds.
