Life of Life

What's that, which, ere I spake, was gone!
So joyful and intense a spark
That, whilst o'erhead the wonder shone,
The day, before but dull, grew dark?

I do not know; but this I know,
That, had the splendour lived a year,
The truth that I some heavenly show
Did see, could not be now more clear.

This know I too: might mortal breath
Express the passion then inspired,
Evil would die a natural death,
And nothing transient be desired;

And error from the soul would pass,
And leave the senses pure and strong
As sunbeams. But the best, alas,
Has neither memory nor tongue!
