Defining Beauty Poem by Mary Champion

How can I assess beauty?
What unit of measurement
would be most appropriate?

Beauty has many forms.
I have seen it in the glory of a sunset.
I have heard it in intoxicating music.
I have smelt it in the perfume of a rose.
I have tasted it in food's enticing flavours.
I have felt beauty in a flash of insight,
in the velvet touch of a baby's skin,
in a novel and pleasing arrangement of words.

All my senses are alive to beauty -
attuned to its presence,
they recognise and take delight in its harmony.
But where are the words to describe its essence?
Never mind the units to measure it.
