10 Things of Creation

By ten things was the world created,
by wisdom and by understanding, and
by reason and by strength (Gevurah), by
rebuke and by might,
by righteousness and by judgment,
by loving kindness and compassion.(12)
The connection with the sefirot doctrine is so strong as to suggest that the sefirot are in reality an hypostatization of these aggadic and talmudic ideas. Indeed the talmudic view that God has essentially two basic traits - chesed (loving kindness) and din (strict judgment) - is adopted by the Bahir and subsequent Kabbalists in the view that these sefirot are the two most essential for the creation of the world. http://www.aril.org/Drob.htm
