Bilti mugah "unedited" or "not reviewed.

בלתי מוגה

In Chabad literature and context, בלתי מוגה refers to teachings, talks, or writings of the Rebbe that have not undergone formal editing or review by the Rebbe himself. While these texts or talks may have been transcribed or recorded, they are considered less authoritative compared to those that were personally reviewed and edited (מוגה) by the Rebbe. The distinction is important for accuracy and reliability in Chassidic study.
