Happiness is a matter of one's most ordinary everyday mode of consciousness being busy and lively and unconcerned with self. To be damned is for one's ordinary everyday mode of consciousness to be unremitting agonizing preoccupation with self.
Happiness is a sunbeam, Which may pass through a thousand bosoms Without losing a particle of its original ray Nay, when it strikes on a kindred heart, Like the converged light on a mirror, It reflects itself with redoubled brightness. It is not perfected till it is shared.
Happiness is always a by-product. It is probably a matter of temperament, and for anything I know it may be glandular. But it is not something that can be demanded from life, and if you are not happy you had better stop worrying about it and see what treasures you can pluck from your own brand of unhappiness.
Happiness is an inner perception, inner joyfulness. We are happy when we express our kindness unconditionally. We are happy when we love someone unconditionally. By becoming the source of happiness for someone, we become happy. Happiness is the purpose of every creation.
Happiness is heart-warming/healthful i.e. happiness is emotionally rewarding/uplifting and good for your health. Moreover, the more happier you are, the more healthier you will be/remain. So, dare to be/remain happy always and never sad.
