Yechidah (Hebrew YChDH, “only one”) in¬†Kabbalistic¬†theory is the highest aspect of the human soul corresponding to the first¬†Sephirah¬†Kether, and is included in the¬†neshamah.

The yechidah closely corresponds to the Neoplatonist concept of the scintilla or synteresis, the spark of divine light at the center of the self. A.G.H.
