In order for there to be a feeling in a person’s heart that he is clearly aware of, there must be a tangible, clear, and active perception in his mind.
Only when a person has a good, clear, and conscious idea of the greatness of God, that He is infinite and bestows life on all, can he attain love and fear of God in the revealed awareness of his heart.
Only when he has a constructed and structured consciousness (Bina), and it is connected (Da’at) to the tangible reality that he sees with his eyes, will
it draw forth and reveal the feelings of love and fear in his heart.
Rabbi Adin Steinsaltz
