Chassidus in general, and Chabad
Chassidus in particular, is an all-embracing world outlook
and way of life which sees the Jew's central purpose as the unifying
link between the Creator and Creation. The Jew is a creature of "heaven"
and of "earth,"of a heavenly Divine soul, which is truly
a part of G-dliness, clothed in an earthly vessel constituted of a
physical body and animal soul, whose purpose is to realize the transcendency
and unity of his nature, and of the world in which he lives, within
the absolute Unity of G-d.
The realization of this purpose entails a two-way correlation: one
in the direction from above downward to earth; the other, from the
earth upward. In fulfillment of the first, man draws holiness from
the Divinely-given Torah and commandments, to permeate there with
every phase of his daily life and his environment - his "share"
in this world; in fulfillment of the second, man draws upon all the
resources at his disposal, both created and man-made, as vehicles
for his personal ascendancy and, with him, that of the surrounding
world.
