Nothing is more memorable than a smell. One scent can be unexpected, momentary and fleeting, yet conjure up a childhood summer beside a lake in the mountains; another, a moonlit beach; a third, a family dinner of pot roast and sweet potatoes during a myrtle-mad August in a Midwestern town. Smells detonate softly in our memory like poignant land mines hidden under the weedy mass of years. Hit a tripwire of smell and memories explode all at once. A complex vision leaps out of the undergrowth.

[On gardens:] I think they're sanctuaries for the mind and spirit. ... It's easy to feel wonder-struck in a garden, especially if you cultivate delight.

When you consider something like death, after which (there being no news flash to the contrary) we may well go out like a candle flame, then it probably doesn't matter if we try too hard, are awkward sometimes, care for one another too deeply, are excessively curious about nature, are too open to experience, enjoy a nonstop expense of the senses in an effort to know life intimately and lovingly.

Smell is the mute sense, the one without words.

We think of it as a sort of traffic accident of the heart. It is an emotion that scares us more than cruelty, more than violence, more than hatred. We allow ourselves to be foiled by the vagueness of the word. After all, love requires the utmost vulnerability. We equip someone with freshly sharpened knives; strip naked; then invite him to stand close. What could be scarier?

To begin to understand the gorgeous fever that is consciousness, we must try to understand the senses and what they can tell us about the ravishing world we have the privilege to inhabit.

Happiness doesn't require laughter, only well-being and a sense that the world is breaking someone else's heart, not mine.
