Musar su Deuteronomio 6:4

Then when a person leaves his house let him pray this short prayer: “Master of the Universe! Please have pity upon me and spare me from the evil impulse and all its minions, Amein.” Or else let him recite the first paragraph of the Shema: “Hear, Yisroel, Hashem is our God, Hashem is one” until the verse “You shall write them upon the door posts of your house and upon your gates” (Devarim 6:4-9). Then he will be spared that day from all iniquity and guilt.

These commandments are divided into three groups of which some aim at perfecting our souls, some at perfecting our bodies, and others at ensuring that our property will be "pure", i.e. that we will not be guilty of robbery and dishonesty. Concerning these three aspects of perfection, the Torah says: "Love the Lord your G–d with all your heart, i.e. the seat of your physical life, with all your soul, i.e. the seat of your spiritual life, and with all your might, i.e with all your economic assets" (Deut 6,4).

כי נר מצוה ותורה אור, ודרך חיים תוכחת מוסר, We have already mentioned that the weekly perusal of the relevant Torah portion has to include three distinct approaches. First and foremost, one must study the relevant commandments contained in the פרשה, be they positive or negative. This part of the weekly study comes under the heading of כי נר מצוה, “for the commandment is a lamp." Secondly, one must try to understand both the obvious and the more mystical significance of these commandments and their influence on our relationship with the "higher" world, each person according to his ability. In that connection it is important to be aware that no one part of the Torah is less important than any other part. If the Torah tells us for instance, that "the concubine of Eliphaz was called Timnah" (Genesis 36,12), this is no less important a sentence than שמע ישראל ה' אלוקינו ה' אחד, "Hear O Israel the Lord our G–d the Lord is One" (Deut 6,4). Every single part of the Torah reveals matters relevant to our world as well as matters relevant to the "higher" world. Our sages have given us an example of the importance of the verse quoted from Genesis by showing that the name of that concubine תמנע is composed of the first letters of certain words in the verse תורת השם תמימה משיבת נפש, עדות השם נאמנה מחכימת פתי (Psalms 19,8). The implication is that "the Torah is so perfect in totality" i.e. תורת ה' תמימה, that any part of it is מחכימת פתי, "makes the simple wise." All of Torah from beginning to end is משיבת נפש "renews life." The "life" referred to is the life in the "higher" regions. Anyone endowed by G–d with wisdom, חכמה, will be granted the kind of intelligence that enables him to touch base with חכמה-תבונה-ודעת. This is all included in the concept of תורה אור, that Torah is light. Any recipient of this "light," will discover in Torah the three dimensions of knowledge we have mentioned.
