Musar su Deuteronomio 30:19

And know that there are sublime virtues given over in the positive commandments such as: The virtues of free choice, as it is stated (Deuteronomy 30:19), “and choose life”; and the virtues of Torah study, as it is stated (Deuteronomy 6:7), “and you shall speak about them;” and the virtues of walking in the ways of the Lord, as it is stated (Deuteronomy 28:9), “and you shall walk in His ways;” and the virtues of contemplation of the greatness of the Lord, as it is stated (Deuteronomy 4:39), “Know therefore this day and keep in mind that the Lord alone is God in heaven above and on earth below; there is no other,” and David said (Psalms 14:2), “The Lord looks down from heaven on mankind to find a man of understanding, a man who seeks God”; and the virtues of remembrance of His kindnesses,” as it is stated (Deuteronomy 8:2), “Remember the whole way,” and it is [also] stated (Deuteronomy 8:6), “And you shall know that the Lord your God disciplines you just as a man disciplines his son,” and David said (Psalms 107:43), “he will contemplate the kindnesses of the Lord,” and said (Psalms 26:3), “For Your kindness is across from my eyes”; and the virtues of holiness, as it is stated (Leviticus 11:44), “and you shall sanctify yourselves and you shall be holy”; and the virtues of worship, as it is stated (Deuteronomy 10:20), “and He shall you worship;” and the virtues of fear, as it is stated (Deuteronomy 10:20), “And you shall fear the Lord”; and the virtues of love, as it is stated (Deuteronomy 6:5), “And you shall love the Lord, your God;” and the virtues of clinging, as it is stated (Deuteronomy 10:20), ”to Him shall you cling.” There are several levels to each of these, as will be explained, with God’s help. And man was created for the sake of these virtues, as it is stated (Isaiah 43:7), “All who are linked to My name, whom I have created for My glory.” And what is the hope of a creation if it does not make the things for which it was created, the toil of his soul and his main occupation?

The eleventh—We find in the Scripture (Deuteronomy 30:19), “Therefore choose life that thou mayest live, thou and thy seed.” And it says (Ibid., 5:30), “That ye may live.” And it says (Ibid., 8:1), “We will live and multiply.” And it says (Ibid., 5:16), “That thy days may be long.” We see that the wicked seem to live like the righteous, and, in many cases, they enjoy the goodness of the world. Therefore, the life of which the Scripture speaks must be the life that comes after death.

And when he reflects constantly and weighs the smallness of the reward of transgression in this world against its eternal loss, the father will certainly not pay heed to the voice of the "whisperers" and will choose life, to strengthen his son in the Torah of the L-rd, which is the true life, as it is written (Mishlei 3:18): "It is a tree of life to those who hold fast to it." And if he eats of its fruits, he lives forever, as Chazal have formulated for us in the blessing "And eternal life did He plant in our midst." And then he will merit eternal life, he and his seed, as it is written: "And he will give pleasure to your soul," and, as it is written in the Torah (Devarim 30:19): "And choose life, so that you live, you and your seed."
