Akshara (अक्षरा) is the Sanskrit word for "imperishable" — also the term for a syllable or letter of the alphabet. In Vedanta, Akshara refers to the unchanging supreme reality (Brahman).
Akshara Haasan (born 1991) is the Indian actress, daughter of Kamal Haasan.
Akshara 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 Akshara reduce to 5, The Seeker. This is a traditional interpretive system, not a factual claim about the name.
