"It's like this for a reason! My heart is invincible and my spirit is undying! I may get hurt, but it'll never die out!"
A personal sketch I worked on recently, wanted to practice expressions a lil bit. Don't worry, I am fine! The meaning here isn't about heartache, instead it's about being able to keep going despite repeated setbacks.
Cruxes chest symbols are cabalistic, and can be a reflection of their vices or virtues. The Leukos Arsenikon (White fur, black markings) often have the crossed infinity, which I've always taken to heart as an undying spirit.
