The human heart is one of the most miraculous organs in existence, not only because of its biological function but also due to the mysterious aura it has carried through literature, philosophy, and spirituality. Scientifically, the heart is a powerful muscular pump, slightly larger than a clenched fist, beating about 100,000 times per day and circulating approximately 2,000 gallons of blood through a vast network of vessels that could wrap around the Earth twice.
