心：KOKORO/SIN is a KANJI character meaning mind, heart or soul. Learn and exercise this hand order and surprise your Japanese friends.
This character had made from the anatomical shape of human heart. I wonder why ancient Chinese people got the chance to see the human heart.
KOKORO is also a radical to make other KANJIs which you do not see so often on the street signs but these KANJIs (with KOKORO as radical) will help you to understand what Japanese people recognize the world an human relations.
For the first hand, can you find KOKOR in 愛 AI/E ?
AI corresponds to the English word "love" but I do not think 愛 and love are just the same.
Also, can you find KOKORO in 優:YUH/YASA(SII）; meaning "kind" or "kindly".
