Having restrained the objects of the senses and made the mind wave-less, he stood established within himself—entering, by the Self, into the Deva who is the very treasure-house of austerity (tapas).
Lomaharṣaṇa (Sūta), narrating to the sages (deduced)
Tirtha: Antar-tīrtha (inner tīrtha) of Śiva’s samādhi (implied)
Type: kshetra
Scene: A contemplative tableau: the senses withdrawn, the mind rendered wave-less; the practitioner’s awareness ‘enters’ the deity—Śiva as the treasury of tapas—suggested through stillness rather than action.
Sense-restraint and inner stillness culminate in absorption in the Divine—tapas is inward mastery, not mere hardship.
No particular site is named; the verse presents an inner tīrtha—stilling the mind and turning inward to Śiva.
No external rite; the implied discipline is indriya-nigraha and meditative absorption.
