According to the Hindu scriptures, there are 7 continents or dvipas named:
- Jambu ("Indian Blackberry tree")
- Plaksha ("Ficus religiosa (Peepal) tree")
- Shalmali ("Bombax tree")
- Kusha ("grass")
- Kraunca ("Mountain")
- Shaka ("Pine tree")
- Pushkara ("Maple tree")
Each continent is surrounded by a particular liquid. Jambudvipa is surrounded by an ocean of salt water. Kraunchadvipa is surrounded by an ocean of milk.
Krauñcadvīpa is surrounded by an ocean of milk as broad as the island itself - Bhagavata Purana
Hindu priests and scholars have determined that the North American continent is Kraunchadvipa. Before poojas, temple priests recite a "sankalpa", announcing the time, location, yuga, etc of the pooja or yajna they are about to perform. In India they say "Jambudvipe, bharata varshe", etc. In the US, they say "Kraunchadvipe, ramanakavarshe", etc.
My question is, how did they determine that North America is Kraunchadvipa? This continent is not surrounded by an ocean of milk. It is surrounded by salt water just like Jambudvipa.
