Feelings, yes the heart is the center where feelings are. Like one of the lyrics of an old song that we know "Feelings, nothing more than feelings, trying to forget my feelings of love" by Morris Albert. However, from one sentence of lyrics in this song we can see and express how feelings produce what is called love.
When someone feels what is called love, they might feel how love makes themselves a part that cannot be touched without being made or intended. Even the language of love that is present is something that maybe in this world we can't import it. Because love comes unexpectedly and unexpectedly, sometimes it even comes from what is said undesired.
We can't import it of love, whether it's sweet or bitter. Because love runs by itself like the flow of water in a river that always looks for where the final estuary is. And the heart is the final place where love will be created. This is not limited to love between two people, but it embraces everything about the meaning of love for every creature.
