This quote means (to my understanding)
that as simple as kindness is, it is the most beautiful and heart warming thing there is. It makes you feel fuzzy inside in a good way, when you see a kind action or when you make a kind action towards another. No matter how small. the action may be. A snowflake is smaller than a pinkie tip but those little specs can flood a city in beautiful whiteness. Just like a smile or a good action towards another can flood someone with happiness
