This leaf made me think of the heart, intricacies of the veins and arteries, so very small, yet what gives us life...
"The heart is a myogenic muscular organ found in all animals with a circulatory system (including all vertebrates), that is responsible for pumping blood throughout the blood vessels by repeated, rhythmic contractions. The term cardiac (as in cardiology) means "related to the heart" and comes from the Greek καρδιά, kardia, for "heart".
The vertebrate heart is composed of cardiac muscle, which is an involuntary striated muscle tissue found only in this organ, and connective tissue. The average human heart, beating at 72 beats per minute, will beat approximately 2.5 billion times during an average 66 year lifespan, and weighs approximately 250 to 300 grams (9 to 11 oz) in females and 300 to 350 grams (11 to 12 oz) in males."
"Keep your heart open for as long as you can, as wide as you can, for others and especially for yourself."
"When you wholeheartedly adopt a 'with all your heart' attitude and go all out with the positive principle, you can do incredible things."
-Norman Vincent Peale
"When the heart of your heart opens, you can take deep pleasure in the company of the people around you . . . When you are open to the beauty, mystery, and grandeur of ordinary existence, you "get it" that it always has been beautiful, mysterious, and grand and always will be."
-Timothy Ray Miller
