*HIDDEN - also see MYSTERY, SECRET, REVELATION, SEPARATE, BECOMING
The soul that sees Him [One] everywhere [many] is one of love's secrets which is only known of those who have experienced it. The simple vision [knowledge] of pure love does not stop at the outer husk of creation; it penetrates to the divinity which is hidden within. (p305) To know the hidden unity in the Eternal Being is to live at its fullest the Illuminated Life, enjoying "all creatures in God and God in all creatures" - the sense of a unity in separateness. The self becomes conscious of the World of Becoming in which the little individual life is immersed into the great and many-coloured river of life. (p309)(Mysticism)
Hiddenness makes creation possible because God can become "revealed" in a diversity of limited ways, which then form the building blocks of creation. (Wikipedia - Kabbalah)
Things are hidden in the ordinary, common, or frequent. For example, things are hidden daily in Lord's prayer we say "forgive us as we forgive" but we don't realize/meditate on the importance and meaning of "forgiving" (to err is human, but to forgive is divine) nor of "us" (not I, but we). We are all in this life and struggle for salvation together. (Randy)
