"After being born in our world, one is obliged to change
his heart from egoistic to altruistic, while living in
this world. This is the purpose of his life, the reason
behind his appearance in this world, and it is the goal
of all creation. A complete replacement of egoistic
desires with altruistic ones is called "gmar tikkun" (the End of
Correction). Every individual and all of humanity must attain it in this world together. Until one achieves
this, he will continue to be born into this world. The
Torah and all the prophets speak exclusively of this.
The method of correction is called “Kabbalah.”
Rav Yehuda Ashlag (Baal HaSulam)
