Cardially.

Happy Eid day from the depth of right & left ventricles,

wrapped with the ribbons of purkinje fibers and sealed in pericardium.

Decorated with SA and AV nodes with a glitter topping of pericardial fluid

and cusps of mitral and tricuspid valves.

In short ap ko teh-e-dil se EID MUBARAK ho 🙂
