G-d’s assistance in helping one mend his character:[1]
It is not possible for one to completely overturn his nature and natural character traits without the help of G-d. [Thus, in reference to experiencing love for G-d from even one’s animal soul, it is not possible for one to completely rid himself of lust for physical pleasures and transform his lust for only G-d and spirituality without G-dly assistance.] This G-dly assistance is received by one’s soul upon him performing Torah and Mitzvah’s which sends a ray of G-dliness onto the soul and helps it become elevated and incorporated above. The performance of the Torah and Mitzvahs, including the negative commands, jolts the power of fire above in heaven to be drawn below and to then consume and burn the animalistic energies of one’s animal soul and elevate it to its root and source. This then will allow the attributes of G-d to shine within his soul, as opposed to the natural attributes of his soul.
