A person’s soul is “an actual part of G-d.”
~ Rabbi Schneur Zalman of Liadi , Tanya, Ch. 2
The beginning of repentance which immediately illumines the darkness is that man return to himself, the root of his soul, and he will at once return to G-d, to the SOUL OF ALL SOULS. This is true for the individual, the entire nation, for all of humanity, for the perfection of existence as a whole; its ruin always comes when it forgets itself. ~ Rav Abraham Isaac Kook, Orot HaTeshuva Ch. 15:10
