DEUT219 Love Hashem. In the words of the Sifri [i.e., a collection of midrash on Deuteronomy—AJL], “How does a person go about achieving love for Hashem? [Hashem commands] ‘And these words that I command you today shall be on your hearts.’” That is, by means of studying and reflecting upon the Torah, love of Hashem is certain to be generated in one's heart. Having achieved this love, one feels obligated to do as Avraham Avinu--to help others to achieve this love and to guide them towards devoted service of Hashem. Key concept is obvious, for unless one loves his Maker, he will not properly fulfill His commandments. It is fitting for a person to put all of his thoughts and energy towards the goal of achieving love for Hashem. He should remind himself at all times that whatever there is in the world--wealth, children, honor or anything else-- all are nothing compared to love for Hashem. At all times, one should strive for wisdom, in order to attain as much recognition of Hashem as possible. In sum, do everything in your power to train your heart so that all day long, your only thoughts are about אמונתו ויחודו-- faith in Him and His One-ness. Try to reach a point that never, even for a moment, you forget your wholehearted love for Him. One violates this mitzvah when one places his affection in materialistic matters, in the fleeting pleasures of the physical world, to selfishly indulge in them not for the sake of Heaven, or one thirsts to obtain honor in this world of lies. By filling one's heart with such desires, one nullifies the positive command to love Hashem, and one’s punishment is great. Like the mitzvah above [See [[DEUT198]] Deuteronomy 6:4 believe CHINUCH 272-3], this one, too, is one of the Torah’s six constant commandments [also cited in the Mishnah Berurah, Siman 1 in the Biur Halachah, s.v. Hu klal.], for love of Hashem must fill our hearts always.
