पुरुषो ऽसि पुरे शेषे त्वं अङ्गुष्ठप्रमाणतः आश्रितश्चैव चाङ्गुष्ठम् ईशः परमकारणम्
puruṣo 'si pure śeṣe tvaṃ aṅguṣṭhapramāṇataḥ āśritaścaiva cāṅguṣṭham īśaḥ paramakāraṇam
तू तोच पुरुष आहेस जो देह-पुरात अंतःस्थित शेषरूपाने वास करतोस; तू अँगठ्याएवढा आहेस. तरीही तो अँगठ्याएवढा आत्मा तुझ्याच आश्रयाने आहे—हे ईश, तू परम कारण आहेस।
Suta Goswami (narrating the Shaiva teaching within the Purva-Bhaga discourse)
It points to the antar-liṅga (inner Linga): Shiva is to be realized not only as an external emblem but as the indwelling Pati who supports even the subtle, thumb-sized self within the body.
Shiva is identified as Īśa, the Paramakāraṇa (supreme causal principle) and the inner ruler; even when the self is described as a subtle ‘aṅguṣṭha-pramāṇa’ presence, that very inner self depends on Shiva as its ground and support.
A meditative (yogic) interiorization is implied—contemplating Shiva as the antaryāmin within the ‘pura’ (body), a key move in Pāśupata-oriented practice where the pashu turns inward to the Pati beyond pasha (bondage).
