ジャンブードヴィーパの広さと同じだけの塩海（クシャーラ・ウダディ）が、それを四方から取り巻いている。さらにその塩海は、二倍の広さをもつプラクシャ島によって囲まれている。まるで城の堀が外側の庭園のような森に囲まれるように。プラクシャ島はジャンブードヴィーパと同じ規模で、そこには黄金のごとく輝くプラクシャ樹がそびえ、その根元では七つの炎をもつ火が礼拝される。この島の統治者は、プリヤヴラタ王の子イダマジフヴァであった。彼は島を七つのヴァルシャに分け、七人の息子の名をそれぞれの地に与えて分封し、のちに自己のヨーガによって世事を退き、主へのバクティ（献身奉仕）に身を捧げた。
FAQs
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.
