The relationship between God's absolute Unity and Divine manifestations may be compared to a man in a room - there is the man himself, and his presence and relationship to others in the room. In Hebrew, this is known as the Shekhinah. It is also the concept of God's Name - it is His relationship and presence in the world towards us. The Wisdom (literally written as Field of Apples) in kabbalistic terms refers to the Shekhinah, the Divine Presence. The Unknowable One (literally written as the Miniature Presence) refers to events on earth when events can be understood as natural happenings instead of God's act, although it is actually the act of God. This is known as perceiving the Shekhinah through a blurry, cloudy lens. This means to say, although we see God's Presence (not God Himself) through natural occurrences, it is only through a blurry lens; as opposed to miracles, in which we clearly see and recognize God's presence in the world. The Holy Ancient One refers to God Himself, Who is imperceivable. (see Minchas Yaakov and anonymous commentary in the Siddur Beis Yaakov on the Sabbath hymn of Askinu Seudasa, composed by the Arizal based on this lofty concept of the Zohar).
