Musar su Deuteronomio 6:6

And in Sifrei, Parshath Ekev we find (Mishlei 5:16): "'Then your springs [of Torah] will spread outwards': Words of Torah are compared to water. Just as water lives forever, so, words of Torah live forever, as it is written (Ibid. 4:2): 'For they are life to him who finds them, and to all of his flesh, healing.' And just as water raises the unclean one from his uncleanliness, so, words of Torah raise one from uncleanliness to purity, as it is written (Psalms 19:10): 'The fear of the L-rd is pure.' [And, just as water purifies a man, though the uncleanliness has spread through all of his limbs, so, Torah purifies a man from the uncleanliness of his sins, even if it has spread throughout him, from the soul of his foot until his head. And just as a man is not purified until the water rises over all of his limbs, and there be nothing intervening between his limbs and the water, so, he must subject all of his body and his limbs, in truth, to Torah, with nothing intervening, as it is written (Devarim 6:6): 'And these words shall be … upon your heart']. And just as water restores a man's soul, so do words of Torah restore a man's soul from the way of evil to the way of good, as it is written (Psalms 19:8): 'The Torah of the L-rd is complete, restoring the soul,.' And just as water is free for the world, so is Torah free for the world, as it is written (Isaiah 55:1): "Ho! all who are thirsty, go to the water [of Torah]." Lest you say: 'Just as water has no valuation, so, Torah has no valuation; it is, therefore, written [to negate this] (Mishlei 3:15): 'It is more precious than pearls and all of your desires cannot be compared to it.'"

And one who takes care to study [words of] Torah and to place them upon his heart merits loving the Blessed L-rd, as we find in Sifrei on (Devarim 6:6): "And let these things that I command you this day be upon your heart," viz.: "From (Ibid. 5): 'And you shall love the L-rd your G-d with all your heart,' I would not know by what means one comes to love the Holy One Blessed be He; it is, therefore, written (5): 'And let these things [(words of Torah)] … be upon your heart.' For by these you come to recognize the Holy One Blessed be He and to cleave to His ways."

We have completed our brief list of the things a man ought to remember always. But everyone should continue to meditate on these according to his wisdom, and he will learn from them all sorts of good and pure qualities, and these will cleanse the soul and will beautify its ugliness. Be ever alert to remember them, and this will bring out in you a superior strength you never knew before. And a man is obligated to keep all of these thoughts in mind constantly, at every hour, at every moment. And he should be careful to remember them with his every breath so that he may never lose his awe and fear and shame before God, who looks upon him at all times. Go forth and learn from what the Torah warned the king to do, as it is written, … "that he shall write him a copy of this law in a book, out of that which is before the priests the Levites. And it shall be with him, and he shall read therein all the days of his life" (Deut. 17:18-19). And it is written, "This book of the law shall not depart out of thy mouth, but thou shalt meditate therein day and night" (Josh. 1:8). And it is written, "And these words, which I command thee this day, shall be upon thy heart; and thou shalt teach them diligently unto thy children, and shalt talk of them when thou sittest in thy house, and when thou walkest by the way, and when thou liest down, and when thou risest up. And thou shalt bind them for a sign upon thy hand, and they shall be for frontlets between thine eyes. And thou shalt write them upon the door-posts of thy house, and upon thy gates" (Deut. 6:6—9). And he has emphasized this matter in connection with the fringes, for it is written, "And it shall be unto you for a fringe, that ye may look upon it, and remember all the commandments of the Lord, and do them" (Num. 15:39—40). And according to this it is proper to remember God at every moment. And it is written, "Let thy garments be always white" (Eccl. 9:8).
