Heart speaks to another Heart in a secret code in the form of beats. The beats are code language of Hearts. Its mandatory beats given as gift by God-datary system with the blessing of Nature. If Heart beats coincide with another Heartbeat, the understanding lasts forever and Hearts are not broken. Always Hearts are pure and don't get polluted unless Hearts made to be polluted willfully. So, one has to preserve the Heart like a God in the Temple.
(It's True, that Heart Speaks.)
Some people have the coldest smiles, but have the tenderest hearts. And many have the most tender smiles, but carry the coldest hearts. You cannot judge a man by his smile, but you can judge a man by his heart. The smallest actions reveal the most about a heart's true color, so pay attention to them. Actions are the true words of the heart.
