The great unabridged Oxford English Dictionary contains half a million words. Among all these, one of the most difficult to define is “happiness.” It is easy enough to find a purely verbal definition such as “a feeling of pleasure or contentment” but that is superficial. Any state of mind is hard to describe but happiness is perhaps the hardest. It is not necessarily associated with any physical state – the possession, for instance, of wealth, or power, or high position, or beauty, or outstanding skill. Indeed, often enough, the actual possession of wealth, power, position, genius, or the adulation which beauty attracts, drives happiness away and leaves behind a feeling of sated discontent, a yearning for something even more. Happiness – it is a will-o-the-wisp which as soon as you grasp at it, it disappears.
