Our sages teach, more then the calf wishes to suckle, the cow wishes to nurse – God made reality as Kabbalah teaches, in a male / female dynamic – this refers to: reality is a hierarchy – the level above (be it spiritual universe etc.) are what create the levels below (obviously as we see, how each seed comes from its parent etc.) – however taking the analogy to its quintessential essence, this parallels the God/man relationship
