Heart

Came across this conversation between Rukia and Kaien-Dono [Manga Bleach] which I find rather meaningful.

Where do you believe the "Heart" lies?

Think about it...

Every time you and I connect with each other,
A little bit of Heart is born between us.
Heart isn't something inside you.
But
whenever you think,
whenever you remember someone,
That's when Heart is born.
If,
you were the only one alive in this world,
Heart wouldn't exist now, would it?
