The symbol of the ever changing life is represented best by an ocean tattoo. Life as shifting as the tides and moving sand represents a woman's resiliency in an uncertain world (also see water tattoos: http://www.girl-tattoos.com/Water_Tattoos.php)
Without the water of the ocean life wouldn't be possible. Washing away the dirty things in girl's life the ocean can show a woman's purification and purity. Considered a very feminine tattoo girls can choose to splash, wave, ripple, or even ink an entire ocean. When it comes to placing an ocean tattoo on your canvas there are plenty of options and things to consider.
The belief in purity and cleaning ones soul in the salt water of the sea has been an idea that has existed for thousands of years, and inking an ocean tattoo is a great way to etch your canvas in the sands of time.
