Harleen is a Punjabi Sikh name meaning "absorbed in God" or "merging with God" — combining har (God) and leen (absorbed). A concept of Sikh devotion.
Harleen is widely used in Sikh communities.
Harleen 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 Harleen reduce to 9, The Giver. This is a traditional interpretive system, not a factual claim about the name.
