Eshana is from the Sanskrit eṣaṇā (एषणा — desire, seeking, aspiration). Eshana Kapoor — modern Indian-American figure. Eshana in modern Indian culture — appears widely across contemporary Indian literature, film, and digital media. Princess Eshana — modern Hindu philosophical heritage naming.
Eshana 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 Eshana reduce to 3, The Communicator. This is a traditional interpretive system, not a factual claim about the name.
