We must not part as others do

We must not part as others do,
With sighs and tears, as we were two:
Though with these outward forms we part,
We keep each other in our heart.
What search hath found a being, where
I am not, if that thou be there?

True love hath wings, and can as soon
Survey the world as sun and moon,
And everywhere our triumphs keep
O'er absence which makes others weep:
By which alone a power is given
To live on earth, as they in heaven.
