What is happiness?

Happiness is...pure and innocent;
It is worldly and wise;
It is in giving, and in receiving;
It is in loving, and in being loved;
It can be tangible, yet untouchable;
It can appear as being or as energy;
It is subtle, yet so powerful;
It is abundant, yet hard to find;
It says a million words, yet can be painfully silent;
It is always welcome, although the invitations get lost;
Dark is a world without it;
Yet, a world without dark will never see the light.
