Gandhari (गान्धारी) means "princess of Gandhara" (modern Kandahar). The wife of the blind King Dhritarashtra in the Mahabharata — on learning of her husband's blindness, she bound a cloth over her own eyes for life, refusing to enjoy what he could not see. Mother of the 100 Kauravas. Her curse on Krishna at the war's end destroyed the Yadava clan.
Featured throughout the Mahabharata.
Gandhari 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 Gandhari reduce to 8, The Visionary. This is a traditional interpretive system, not a factual claim about the name.
