חסידות אויף משלי 3:3

And the heart is pitied in mercy, and impacts the hot speech, as in the aspect of "My heart grew hot within me; a fire blazed in my thoughts; then I spoke out with my tongue" (Psalms 39:4). And in this heart is written all explanations (interpretations) of the Torah, as in the aspect of "Write them on the tablet of your heart". (Proverbs 3:3).
