How can an ocean stand upside down?

God's Bucket

If this worldWas not held in God's bucketHow could an ocean stand upside downOn its head and never lose a drop?If your life was not contained in God's cupHow could you be so brave and laugh,Dance in the face of death?There is a private chamber in the soulThat knows a great secretOf which no tongue can speak.Your existence my dear, O love my dear,Has been sealed and marked"Too sacred," "too sacred," by the beloved—To ever end!Indeed GodHas written a thousand promisesAll over your heartThat say,Life, life, life,Is far too sacred toEver end.
 
-- Hafiz, 13th century Sufi Poet
