सप्तद्वीप-समुद्र-प्रमाणम्: प्लक्षादि-द्वीपवर्णनं, लोकालोक-सीमा, चन्द्र-समुद्र-वृद्धिक्षयः
त्रेतायुगसमः कालः सर्वदैव महामते प्लक्षद्वीपादिषु ब्रह्मञ् शाकद्वीपान्तिकेषु वै
tretāyugasamaḥ kālaḥ sarvadaiva mahāmate plakṣadvīpādiṣu brahmañ śākadvīpāntikeṣu vai
O wise Brahman, in Plakṣa-dvīpa and the other islands, and likewise in the regions bordering Śāka-dvīpa, time is ever of the measure of the Tretā-yuga.
Sage Parāśara (teaching Maitreya)
Speaker: Parasara
Topic: Quality/measure of time in Plakṣa-dvīpa and other dvīpas; Tretā-yuga equivalence
Teaching: Cosmological
Quality: authoritative
Yuga: Treta
Cosmic Hierarchy: Dvipas
Concept: Yuga-qualities can characterize regions as well as eras; some domains abide perpetually in a Tretā-like order.
Vedantic Theme: Dharma
Application: Seek ‘Tretā-like’ life through truthfulness, ritual discipline, and social responsibility even amid Kali-like conditions.
Vishishtadvaita: Dharma manifests in graded fullness across loci within one real cosmos sustained by the Lord’s governance (niyati) and grace.
Vishnu Form: Narayana (cosmic)
This verse indicates that different island-continents experience different temporal and dharmic conditions; in Plakṣa-dvīpa and regions near Śāka-dvīpa, the prevailing measure is consistently Tretā-like, reflecting a distinct cosmic order across realms.
In the geographic-cosmological narration of Ansha 2, Parāśara describes dvīpas and their characteristic conditions; here he states that the time-measure in specific dvīpas corresponds to a particular yuga, implying that yuga-qualities are not uniform everywhere.
Even when the verse is descriptive, the Vishnu Purana frames cosmic order—space, time, and dharma—as upheld by the Supreme Lord Vishnu; yuga-structure and its realm-wise variations are expressions of his sustaining sovereignty.
