सप्तद्वीप-सप्तसमुद्र-वर्णनम् तथा प्रियव्रतवंश-राज्यविभागः
सप्त मेधातिथेः पुत्राः प्लक्षद्वीपेश्वरा नृपाः ज्येष्ठः शान्तभयस्तेषां सप्तवर्षाणि तानि वै
sapta medhātitheḥ putrāḥ plakṣadvīpeśvarā nṛpāḥ jyeṣṭhaḥ śāntabhayasteṣāṃ saptavarṣāṇi tāni vai
Medhātithi had seven sons, kings who ruled as lords of Plakṣadvīpa. Of them, the eldest was Śāntabhaya; and those regions are indeed seven varṣas (sub-lands).
Suta Goswami (narrating the Purana to the sages at Naimisharanya)
It situates Shiva’s Purana within a mapped cosmos—showing that the ordered worlds (dvīpas and varṣas) are part of the manifested domain (pāśa) in which the pashu performs dharma and Shiva-puja toward liberation under Pati, Shiva.
Indirectly: by presenting the structured creation, it implies Shiva-tattva as the transcendent Pati who is beyond the divided regions, while the cosmos described here belongs to the field of manifestation traversed by bound souls (pashu).
No specific puja-vidhi or Pashupata Yoga limb is stated; the takeaway is cosmological orientation—creation’s order as the setting where vows, charity, and Shiva-upasana are undertaken for loosening pāśa (bondage).
