Bhuvana (भुवना) is the Sanskrit word for "world" or "earth" — also an epithet of the goddess Bhuvaneshwari, "queen of the universe." Widely used in South India.
Bhuvana Chandra is the Telugu lyricist.
Bhuvana does not currently appear in the US Social Security Administration's top 1,000 girls' names, so we don't publish a US rank or birth count for it. That says nothing about the name's standing elsewhere in the world — only that it sits outside the ranked US data we rely on.

In Pythagorean numerology the letters of Bhuvana reduce to 6, The Nurturer. This is a traditional interpretive system, not a factual claim about the name.
