Lasya (लास्य) is the Sanskrit word for the graceful, feminine dance form — the dance of the goddess Parvati, complementing the vigorous Tandava of Shiva. In Indian classical dance theory, Lasya is the lyrical, gentle dance.
Lasya is widely used in South India.
Lasya 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 Lasya reduce to 4, The Builder. This is a traditional interpretive system, not a factual claim about the name.
