जम्बूद्वीपस्य विस्तारः शतसाहस्रसंमितः स एवं द्विगुणो ब्रह्मन् प्लक्षद्वीप उदाहृतः
jambūdvīpasya vistāraḥ śatasāhasrasaṃmitaḥ sa evaṃ dviguṇo brahman plakṣadvīpa udāhṛtaḥ
The breadth of Jambūdvīpa is declared to be a hundred thousand yojanas; and, O Brāhmaṇa, Plakṣadvīpa is taught to be exactly twice that measure.
Sage Parāśara (speaking to Maitreya)
Speaker: Parasara
Topic: Measurements of Jambūdvīpa and proportional expansion to Plakṣadvīpa
Teaching: Cosmological
Quality: precise
Cosmic Hierarchy: Dvipas
Concept: Cosmic geography is described through proportional measures, conveying an ordered and intelligible universe.
Vedantic Theme: Dharma
Application: Use the idea of proportion and order as a meditative aid to cultivate disciplined thinking and steadiness in practice.
Vishishtadvaita: The cosmos has determinate structure as an expression of the Lord’s will; orderliness reflects divine immanence in the world-system.
It anchors the Purāṇic world-map with a stated scale, presenting cosmic geography as an ordered, intelligible system rather than a random expanse.
He gives a proportional rule: Plakṣadvīpa’s extent is explicitly twice that of Jambūdvīpa, establishing a patterned progression among the dvīpas.
Even when Viṣṇu is not named in the verse, the Purāṇa frames such cosmic order and measure as part of the Supreme Lord’s sustaining governance of the universe.
