Dara is from the Khmer Dārā (តារា — star) — Sanskrit Tārā (star, savior). Dara is one of the Khmer feminine names — central to traditional Cambodian heritage. The Khmer/Sanskrit Tārā refers to the Buddhist female bodhisattva of compassion (Green + White Tara) — central to Mahayana + Vajrayana Buddhism.
Dara 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 Dara reduce to 6, The Nurturer. This is a traditional interpretive system, not a factual claim about the name.
