Kochos/Kochot haNefesh (Hebrew: כוחות הנפש from nephesh-"soul"), meaning "Powers of the Soul", are the innate constituent character-aspects within the soul, in Hasidic thought's psychological internalisation of Kabbalah. They derive from the 10 Sephirot Heavenly emanations of Kabbalah, by relating each quality to its parallel internal motivation in man. The Hasidic discussion of the sephirot, particularly in the Kabbalistically oriented system of Habad thought, focuses principally on the Soul Powers, the experience of the sephirot in Jewish worship.
Among the soul powers, Bittul (Human "self-nullification" of ego), the first revealed power, turns the Ani-"Self" into Ayin-"Nothingness" in the contemplative preparation for experiencing the Divine "Ayin" nullification of Existence. In the elite ideal of Deveikut-"cleaving" to God, the central Hasidic principle in its reinterpretation of Judaism, this inspires the subsequent powers of expression. In Mainstream "Practical Tzadikism", this elite dimension is reserved for the Hasidic leader, with popularised deveikut devotion found instead in the emotional sanctification of life. The Essential Soul Powers are revealed in spiritual Mesirat Nefesh-"Self Sacrifice" in devotional fulfilment through action. Hasidic emphasis on Divine Omnipresence sees the essential Divine purpose embodied only in action, its ultimate mystical stress on action.
