Sapta-dvīpa Cosmography and the Vision of Śvetadvīpa–Vaikuṇṭha
क्रौञ्चद्वीपस्य विस्ताराद् द्विगुणेन समन्ततः / शाकद्वीपः स्थितो विप्रा आवेष्ट्य दधिसागरम्
krauñcadvīpasya vistārād dviguṇena samantataḥ / śākadvīpaḥ sthito viprā āveṣṭya dadhisāgaram
O ihr Brāhmaṇas, Śāka-dvīpa liegt ringsum, indem es die Ausdehnung von Krauñca-dvīpa nach allen Seiten um das Doppelte überragt, und umschließt den Ozean der Dickmilch (Dadhi-sāgara).
Suta (narrating to the sages at Naimisharanya, within the Kurma Purana’s cosmography section)
Primary Rasa: adbhuta
Secondary Rasa: shanta
This verse is primarily cosmographic, mapping the dvīpas and oceans; it does not directly teach Ātman-doctrine, but it supports the Purāṇic vision of an ordered cosmos in which dharma and contemplation can be situated.
No specific yoga practice is taught in this line; it belongs to the Purva-bhāga’s cosmology. In the Kurma Purana, explicit yoga instruction is concentrated later (notably in the Upari-bhāga’s Ishvara Gita and Pāśupata-oriented teachings).
It does not explicitly mention Śiva-Viṣṇu unity; it is a geographic/cosmic description. The Kurma Purana’s synthesis is seen more directly in its theological and yoga sections, while this verse provides the cosmological frame those teachings inhabit.
