Arousing mercy for the plight of the G-dly soul is a means for generating love for G-d (Ch. 45.)

"As water reflects a face so does the heart of a man to his fellow" (Mishlei 27) describes the reciprocal nature of love. When one thinks about G-d's love for us shown at the time of the Exodus, it will cause us to feel love for G-d (Ch. 46.) The Exodus does not only refer to the historical liberation from Egypt but to our personal ability to transcend bodily limitations and be close to G-d in the present (Ch. 47.)
