Two notes on the Incarnation

I recently came across two points about the Incarnation, as present in our Eastern teachings.

1.) Why Mother of God holding the Son? and not just an icon of the Blessed Virgin Mary?
"[T]his icon bears witness to the closeness of God. It gives us confirmation of the fundamental fact relating to our salvation: God became man." Wow, so simple. I guess I never really knew that, or thought about that much.

2a.) As a warning, I do not remember where I read this exactly - perhaps somewhere in the Service Book of the Holy Orthodox-Catholic Apostolic Church, by Isabel Hapgood.

2.) It is often noted that when we Eastern Christians bless ourselves, the thumb, index and third fingers are brought together to symbolize the Trinity; and the remaining two fingers symbolize the two natures of Christ, God and man. What is less often noted, and what I read - somewhere - is that those two last fingers are not only supposed to hang loosely - no! - they are to "dig deep into" the palm of the same hand, in order to symbolize the Incarnation. So when we bless ourselves, not only do we say, "In the name of the Father and the Son and the Holy Spirit," but at the same time our hand gives glory to the Trinity, the Two natures of Christ, and the Incarnation. And that's even before the Trisagion. There is much upon which to reflect when the fingers are so arranged and one is blessing oneself and singing, "Holy God, Holy and Mighty, Holy and Immortal, have mercy on us..." ...especially given that the words usually spoken are, "In the name of the Father..."
As an additional thought: It seems (at least to me) that in our effort to "understand" each Person of the Trinity - or at least given the separate name there is for each Person and that we do not typically use some fuller form to the effect of: "God the Father, God the Son, God the Holy Spirit" - we sometimes lose sigh t(or at least I do), or on occasion are not mindful as we should, of God's unity. Fortunately, our formula for blessing ourselves beautifully unites the Persons into One, Holy God.
