Yechidah (Hebrew YChDH, “only one”) inĀ KabbalisticĀ theory is the highest aspect of the human soul corresponding to the firstĀ SephirahĀ Kether, and is included in theĀ neshamah.

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