Mridula is from the Sanskrit मृदुला (Mṛdulā — tender, soft, delicate, gentle) — from Sanskrit mṛdu (soft/gentle). Mridula is one of the Sanskrit feminine names — central to traditional Hindu heritage. Sanskrit feminine name reflecting Hindu tenderness heritage.
Mridula 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 Mridula reduce to 6, The Nurturer. This is a traditional interpretive system, not a factual claim about the name.
