Dreams, books, are each a world; and books, we know, Are a substantial world, both pure and good: Round these, with tendrils strong as flesh and blood, Our pastime and our happiness will grow.
If happiness always depends on something expected in the future, we are chasing a will-o'-the-wisp that ever eludes our grasp, until the future, and ourselves, vanish into the abyss of death.
Happiness is a state of mind. With physical comforts if your mind is still in a state of confusion and agitation, it is not happiness. Happiness means calmness of mind.
