This artwork beautifully captures profound symbolism! 
 
The snakes depicted around the glass represent the ouroboros cycle, and the process of the infinite cycle of destruction and rebirth we attain in our lives in order to achieve refinement in ourselves as an individual, and a loved one. 
 
The arms are a mix of the dead and the living, representing the strength and support that the ones that we have lost continue to give us even in their absence, and how we continue to carry their legacy and strength in the physical world.
