Prajna (प्रज्ञा) is the Sanskrit word for "wisdom" — specifically transcendent wisdom that perceives ultimate reality.
The Heart Sutra and Diamond Sutra are her core teachings.
Prajna 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 Prajna reduce to 6, The Nurturer. This is a traditional interpretive system, not a factual claim about the name.
