Are there any Buddhist patterns that represent eternity? Do you want photos?

If we have to say eternity, it is our original pure and perfect heart, which is the meaning of "nirvana" in Buddhism. Besides, nothing can be called eternity. In Buddhism, bells and pestles, crystals, round mirrors and other things are often used to refer to. If you want a pattern, you can search for "Tancheng" or "Datura" and choose your favorite.
