A concealed world. On the Possuk in Tehilim (106:48) בָרוּךְ ה׳ אֱלֹקֵׁי יִשְרָאֵׁל מִן הָעוֹלָם וְעַד הָעוֹלָם “Blessed is HaShem, G-d of Yisroel from the world until the world” there is a Zohar (Vol 1, 153:2) that explains: “from the world” refers to the upper concealed world; “until the world” refers to the lower revealed world. The Rebbe explains in a Sicha in 5717 (Parshas Korach) that there are several levels that are explained through several parables that explain the contrast between these two. The difference between the (letters) [concepts] in one’s mind versus the letters of speech. The difference between the sun and the light which comes off it. The difference between the great light which eyes let in versus their description in Rabbinic maxims referring to them as blind. The difference between a protrusive stamp and the concave impression it makes in a wax seal. In different spiritual worlds these are represented in different ways.

Revealed world. It is explained in Chassidus that the difference between the revealed world and the concealed world is similar to our world on earth and the world that can be found in the sea, as the Talmud states that everything that can be found on earth can also be found in the sea, except in the sea everything is concealed.
