तस्मात्तपः करिष्यामि यदसाध्यं सुरैरपि । स्वपुत्रं स्वे पदे धृत्वा ततश्चक्रे तपो महत्
tasmāttapaḥ kariṣyāmi yadasādhyaṃ surairapi | svaputraṃ sve pade dhṛtvā tataścakre tapo mahat
เพราะฉะนั้นเราจักบำเพ็ญตบะอันแม้เหล่าเทวะก็ยากจะบรรลุได้ ครั้นตั้งบุตรของตนไว้ในตำแหน่งของตนแล้ว เขาจึงเริ่มตบะอันยิ่งใหญ่
Narrator (with embedded resolve of Viśvāmitra)
Scene: A ruler/householder ceremonially places his son on the seat of authority, then turns away toward the forest with staff and waterpot, signaling the start of ‘mahat tapas’.
True pursuit of spiritual elevation requires sacrifice, responsibility, and sustained austerity.
The verse does not name a tīrtha; it narrates the preparatory act leading into sacred practice.
Tapas (austerity) is the prescribed practice in principle, without a specific vrata-method described.
