The five levels of the soul in Kabbalah

Kabbalah describes the soul in five levels, from bottom to top: Nefesh (life force), Ruach (spirit, emotion), Neshamah (breath, intellect), Chayah (the living one) and Yechidah (the single one). The five names come from the Midrash Bereshit Rabbah (14:9). Kabbalah assigns each level to a Sephirah on the Tree of Life, to one of the worlds and to a letter of the divine name.

The soul levels at a glance

Level	Meaning	Sephirah	World	Letter

Chayah	Living one, encompassing soul	Chokmah	Atziluth	Yod (י)

The worlds are explained in the post on the four worlds of Kabbalah, the letters in the one on the Tetragrammaton.

Where the five names come from

The Midrash Bereshit Rabbah (14:9) says the soul is called by five names and explains each: Nefesh is the blood ("for the blood is the nefesh", Deuteronomy 12:23), Ruach rises and descends (Ecclesiastes 3:21), Neshamah is a person's character, Chayah stays alive in the body when all the limbs die, and Yechidah is single while all the limbs come in pairs. There they are still five names for the same soul. The Zohar works mainly with the three lower levels, Nefesh, Ruach and Neshamah; the Lurianic Kabbalah of the 16th century maps all five onto the worlds and Sephiroth, as in the table above.

1. Nefesh – the life force

Nefesh (נֶפֶשׁ) is the lowest level: the life force that animates the body, with instinct, hunger, sleep and self-preservation. The Torah already links it to the blood ("for the blood is the nefesh", Deuteronomy 12:23). On the Tree of Life, Nefesh belongs to Malkuth, the Kingdom, and to the world of Assiah, the world of action.

2. Ruach – emotion and spirit

Ruach (רוּחַ, also: wind, spirit) is the level of feelings and moral sense: compassion, love, anger, conscience. The Midrash explains the name by saying Ruach rises and descends (Ecclesiastes 3:21), as the wind does. Ruach corresponds to the six middle Sephiroth from Chesed to Yesod, with Tiphereth at the centre, and to the world of Yetzirah, the world of formation. Cultivating Ruach means refining these forces and letting them serve higher values.

3. Neshamah – the divine breath

Neshamah (נְשָׁמָה, breath) is the level of intellect and spiritual insight. In the Midrash it stands for a person's character (some translations say: intellect); in Kabbalah it is the part that asks after the divine and receives understanding. It corresponds to Binah (Understanding) and the world of Beriah, the world of creation. According to this teaching, prayer, study, ethical living and meditation open access to it.

4. Chayah – the living one

Chayah (חַיָּה, "living") is so called because, according to the Midrash, it stays alive in the body when all the limbs die. In Kabbalah it counts as an encompassing soul: it does not dwell in the body but surrounds it like a light. It corresponds to Chokmah (Wisdom), the first flash of an insight, and to the world of Atziluth.

5. Yechidah – the single one

Yechidah (יְחִידָה, "the single one") is the highest level: the essence of the soul, at one with the divine. The Midrash explains the name by saying that all the body's limbs come in pairs, but the soul is single. It corresponds to Kether (Crown) and to Adam Kadmon, the primordial human above the four worlds, close to Ain Soph. Mystical traditions describe this level as an experience of unity.

The five levels in daily life

According to this teaching, most people live mainly on the levels of Nefesh and Ruach; the higher levels are states rather than stable achievements. A simple question helps with self-reflection: from which level am I responding right now – instinct (Nefesh), emotion (Ruach) or deeper insight (Neshamah)?

In the Lurianic teaching the levels can also return separately; more on that in the post on Gilgul, reincarnation in Kabbalah. The Sephiroth and worlds are explained in the Kabbalah library.

FAQ: the five levels of the soul

What is the difference between Nefesh, Ruach and Neshamah?

Nefesh is the body's life force, Ruach the level of feelings and conscience, Neshamah the level of intellect and spiritual insight. On the Tree of Life they correspond to Malkuth, the six middle Sephiroth and Binah.

Where do the names of the five soul levels come from?

From the Midrash Bereshit Rabbah (14:9), which gives five names for the soul and explains each. Mapping them to Sephiroth and worlds came later in Kabbalah and was worked out in the Lurianic teaching.

Are all five soul levels present in every person?

According to Kabbalah all five are present, but not equally awake in everyone. Everyone experiences Nefesh and Ruach; Neshamah opens through spiritual work; Chayah and Yechidah are considered rare experiences.

How do the soul levels relate to the Tree of Life?

Nefesh corresponds to Malkuth, Ruach to the six middle Sephiroth around Tiphereth, Neshamah to Binah, Chayah to Chokmah and Yechidah to Kether.

Is Yechidah the same as enlightenment?

The Yechidah level resembles what many traditions call mystical union: the experience that the separation between self and divine source falls away. In the kabbalistic view it is, for most people, a moment rather than a lasting state.
