Is there anyone in this world who will own that he has no feeling? And yet there are hearts of rock and of iron, of earth and of diamond, of silver and of gold, of wax and of paper. As many objects as there are in this world, so many kinds of hearts there are; one heart is not like the other. There are some objects that hold fire longer, there are others which burn instantly. There are objects which will become warm and cold in a moment; others, as soon as the fire touches them, will melt, and others again one can mold and turn into ornaments. So is the heart-quality. Different people have different qualities of heart, and by the knower of hearts each is treated differently. But since we do not think about this aspect of feeling, we take every man to be the same. Although every note is a sound, all notes are not the same, they differ in pitch, in vibrations; so every man differs in pitch, in the vibrations of his heart. According to the vibrations of his heart he is either spiritual or material, noble or common. It is not because of what he does, nor because of what he possesses in this world - he is small or great according to how his heart vibrates.
