the supernal divine forces on high, as the scheme of Yosher underscores the inter-relationship of the sefirot as a unit or body. In this context, the physical upright standing of humans contrasts with the horizontal forms of animals. The correspondence of the sefirot with the physical organs of a human: Inner dimensions and the powers of the soul As all levels of Creation are constructed around the 10 sefirot, their names in Kabbalah describe the particular role each plays in forming reality. These are the external dimensions of the sefirot, describing their functional roles in channelling the divine, creative Ohr (Light) to all levels. As the sefirot are viewed to comprise both metaphorical "lights" and "vessels", their structural role describes the particular identity each sefirah possesses from its characteristic vessel. Underlying this functional structure of the sefirot, each one possesses a hidden, inner spiritual motivation that inspires its activity. This forms the particular characteristic of inner light within each sefirah. Understanding the sefirot throughout Jewish mysticism is achieved by their correspondence to the human soul. This applies to the outer, Kabbalistic structure of the sefirot. It applies even more to their inner dimensions, which correspond to inner psychological qualities in human perception. Identifying the essential spiritual properties of the soul gives the best insight into their divine source, and in the process reveals the spiritual beauty of the soul. In Hasidic thought these inner dimensions of the sefirot are called the Powers of the Soul (). Hasidism sought the internalisation of the abstract ideas of Kabbalah, both outwardly in joyful sincerity of dveikus in daily life, acts of loving-kindness and prayer; and inwardly in its profound new articulation of Jewish mystical thought, by relating it to the inner life of man. Articulation of the sefirot in Hasidic philosophy is primarily concerned with their inner dimensions, and exploring the direct, enlivening contribution of each in man's spiritual worship of God. Kabbalah focuses on the esoteric manifestations of God in creation, the vessels of divinity. Hasidut looks at the lights that fill these vessels, how the structures reveal the divine essence, and how this inwardness can be perceived. This difference can be seen in the names of these two stages of Jewish mysticism. "Kabbalah" in Hebrew is derived from "kabal" (to "receive" as a vessel). "Hasidut" is from "chesed" ("loving-kindness"), considered the first and greatest sefirah, also called "Greatness", the wish to
