Rasa is from the Lithuanian rasa (dew) — also the Sanskrit rasa (essence, juice, aesthetic flavor). 200 BCE-200 CE) — the treatise on Indian classical performing arts — identifies the nine rasas (navarasa) including love, joy, sorrow, anger, fear, disgust, wonder, peace, and heroism; this concept has influenced Western literary theory through theorists including Susanne Langer. Rasa Veretto — Lithuanian-American figure. Rasa Tagor — Bengali-Sanskrit heritage figure.
Rasa 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 Rasa reduce to 3, The Communicator. This is a traditional interpretive system, not a factual claim about the name.
