The Six Dvīpas Beyond Jambūdvīpa and the Cosmic Boundary of Lokāloka
जम्बूद्वीपोऽयं यावत्प्रमाणविस्तारस्तावता क्षारोदधिना परिवेष्टितो यथा मेरुर्जम्ब्वाख्येन लवणोदधिरपि ततो द्विगुणविशालेन प्लक्षाख्येन परिक्षिप्तो यथा परिखा बाह्योपवनेन । प्लक्षो जम्बूप्रमाणो द्वीपाख्याकरो हिरण्मय उत्थितो यत्राग्निरुपास्ते सप्तजिह्वस्तस्याधिपति: प्रियव्रतात्मज इध्मजिह्व: स्वं द्वीपं सप्तवर्षाणि विभज्य सप्तवर्षनामभ्य आत्मजेभ्य आकलय्य स्वयमात्मयोगेनोपरराम ॥ २ ॥

Jambūdvīpa is encircled by an ocean of salt water (kṣāra-udadhi) equal in breadth to the island itself. That salt ocean is then surrounded by Plakṣadvīpa, twice as broad—like a fortress moat bordered on the outside by a gardenlike forest. Plakṣadvīpa is equal in size to Jambūdvīpa; there rises a plakṣa tree shining like gold, and at its base a fire with seven tongues is worshiped. The ruler of that island was Idhmajihva, a son of Mahārāja Priyavrata. He divided his island into seven varṣas, named them after his seven sons, allotted the regions to them, and then withdrew by inner yoga, dedicating himself to the Lord’s devotional service (bhakti).
In Canto 5, Chapter 20, the Bhagavatam explains that Jambūdvīpa is surrounded by a salt ocean of equal breadth, and beyond it lies Plakṣa-dvīpa, which is twice as expansive and golden in appearance.
The verse identifies the fire-god as “Saptajihva,” meaning “seven-tongued,” describing Agni’s seven flames/tongues as he is worshiped on Plakṣa-dvīpa.
After responsibly delegating duties, Idhmajihva withdraws through ātma-yoga, teaching that leadership should culminate in detachment and inner spiritual practice rather than lifelong attachment to power.
