Secret of the challah of the world. Adam's portion, all souls included within him. Moses' portion, higher than Adam, rectifying that which Adam could not. Challah is an offering to God, so too are those souls which serve God here on Earth. Yet, Adam could only psychologically elevate souls to a certain point. Along came Moses, and introduced higher levels of souls (greater psychological achievements) to humankind. The meaning of Israel, being a chosen nation, it is not a glorious calling, rather it is an obligation and a chore. Moses' accomplishments radiated out from himself and influenced all of collective humanity. The purpose of all religious rituals and observances is for the sake of the greater good of the collective whole. Mashiah comes when humanity, as a whole, accomplishes the great task of collective integration.
