Labyrinths and endings

I finally looked up the Shakespeare quote that was bothering me on Wednesday when thinking about the labyrinth and Sarah's comment that the meeting of lovers was a sacred space. It is Twelfth Night II. iii The clown sings
"O mistress mine! where are you roaming?
O! stay and hear; your true love's coming,
That can sing both high and low.
Trip no further, pretty sweeting;
Journeys end in lovers meeting,
Every wise man's son doth know.

What is love? 'tis not hereafter;
Present mirth hath present laughter;
What's to come is still unsure:
In delay there lies no plenty;
Then come kiss me, sweet and twenty,
Youth's a stuff will not endure.
