Need

Brief sonnet in no particular form that offers a few thoughts on love.

I need you as rising needs falling, the sea needs the shore.
Nature tortures us; a macabre play at balance, for
Every time together; your presence is to live.
Every time apart; the world leaks light; a sieve.
Describe to me love.
You may find that I already know, but then
Orpheus thought his music the equal of a dove.
Understand that I doubt myself; a fisherman with a holed net.
Still I believe it a river, knifing through the land,
Overflowing with swift waters that beaten, fleeing
Madmen would not dare cross yet
Utterly sane men blindly trek through
Caring not for their safety, and meeting
Halfway: another. Downstream they float as two.
