Arthur Hugh Clough Quote

When panting sighs the bosom fill,
And hands by chance united thrill
At once with one delicious pain
The pulses and the nerves of twain;
When eyes that erst could meet with ease,
Do seek, yet, seeking, shyly shun
Ecstatic conscious unison,—
The sure beginnings, say, be these
Prelusive to the strain of love
Which angels sing in heaven above?

Love and Reason, st. 1 (1844).
