Infinity Tattoo Meaning. Infinity tattoos are steadily on the rise with many people opting to get these in one form or another. The infinity symbol, often used in mathematics, represents a never-ending loop and is depicted as a number 8 on its side. In the tattoo world this can be seen as a symbol of never-ending or limitless possibility. Some cultures also believe it to represent rebirth or reincarnation.
If you and your love want to show commitment to each other in the form of a tattoo, the infinity tattoo is an excellent choice. This is not a tattoo that is strictly for lovers, however. The infinity symbol is a never ending loop, much like the knots and loops in Celtic tattoos. It conveys similar meanings of rebirth and reincarnation as in eastern cultures and religions like Hinduism and Buddhism. This tattoo signifies that we are all eternal whether we are in physical bodies or not.
