(4) Hear, O Israel! The LORD is our God, the LORD alone. (5) You shall love the LORD your God with all your heart and with all your soul and with all your might. (6) Take to heart these instructions with which I charge you this day. (7) Impress them upon your children. Recite them when you stay at home and when you are away, when you lie down and when you get up. (8) Bind them as a sign on your hand and let them serve as a symbol on your forehead; (9) inscribe them on the doorposts of your house and on your gates.

(13) If, then, you obey the commandments that I enjoin upon you this day, loving the LORD your God and serving Him with all your heart and soul, (14) I will grant the rain for your land in season, the early rain and the late. You shall gather in your new grain and wine and oil— (15) I will also provide grass in the fields for your cattle—and thus you shall eat your fill. (16) Take care not to be lured away to serve other gods and bow to them. (17) For the LORD’s anger will flare up against you, and He will shut up the skies so that there will be no rain and the ground will not yield its produce; and you will soon perish from the good land that the LORD is assigning to you. (18) Therefore impress these My words upon your very heart: bind them as a sign on your hand and let them serve as a symbol on your forehead, (19) and teach them to your children—reciting them when you stay at home and when you are away, when you lie down and when you get up; (20) and inscribe them on the doorposts of your house and on your gates— (21) to the end that you and your children may endure, in the land that the LORD swore to your fathers to assign to them, as long as there is a heaven over the earth.
בכל לבבכם ובכל נפשכם. וַהֲלֹא כְּבָר הִזְהִיר "בְּכָל לְבָבְךָ וּבְכָל נַפְשְׁךָ" (דברים ו'), אֶלָּא אַזְהָרָה לַיָּחִיד, אַזְהָרָה לַצִּבּוּר (ספרי):
בכל לבבכם ובכל נפשכם [TO LOVE THE LORD] WITH ALL YOUR HEART AND WITH ALL YOUR SOUL — But has it not already admonished us to love God, by the words (6:5) “[Thou shall love the Lord thy God] with all thy heart and with all thy soul”? But that was an admonition addressed to each and every individual (“with all thy heart”), whilst here it is an admonition addressed to them as a community (“with all your heart”) (Sifrei Devarim 41:29).
From Nifla'ot Gedolot, quoted in Aharon Yaakov Greenberg, Ed. Torah Gems (Itturei Torah), Vol. 3, p. 225
Take heed to yourselves, that your heart be not deceived... (Dest 11:16) The main thing one must take heed of is "yourselves"--the laws between people (ben adam l'haveiro), because a person is generally more careful in laws between people and God (bein adam l'Makom).
Quoted in R. Jules Harlow, Ed. Pray Tell: A Hadassah Guide to Jewish Prayer, pp. 62-63.
How do we understand the second paragraph of the Shema (Deut. 11:13-21)?...Some people have objected to it on the grounds that it seems to promise direct rewards for good behavior and punishment for bad behavior, and thus is belied by our life experience. Indeed, it has been dropped from a number of contemporary siddurim, or downgraded to an "alternative" status. And even in synagogues where it survives, it is usually muttered in an undertone. The same congregations that say the first paragraph after the Shema with vigor and attention, and that focus on the tzitzit mentioned in the third paragraph with strong kavvanah (intention), race through the second paragraph so that few worshippers actually experience its meaning.
Can we learn anew from this passage? First of all, we make many problems for ourselves if we insist on translating YHWH as "Adonai/Lord" (which it usually does not mean) and thus treat YHWH as some power utterly separate from, above, and beyond us. To credit such an all-powerful King/Lord?judge with punishing our every transgression and rewarding our every act of goodness certainly does not accord with what we know happens in our lives. I draw, instead, on the deep sense of YHWH as a Breathing (that is how it comes out if you try to "pronounce" it with no vowels) and hear it as the Breath of Life which is within us, between us, and beyond us. Many of us might hear it as something like "the In-Out Breath that connects all life and being."
Now, with that in mind let us look back at the text. On the one hand, at the level of individuals it is certainly true that the life-process in which we walk and breath often does not let us [reap] what we sow. [Nonetheless,] individuals who put out love and justice into the world are somewhat more likely to bring love and justice back than those who put out anger, hatred, or fear. But it is certainly not a one-to-one certainty, as the Book of Job and the Holocaust remind us.
But at the level of societies as a whole, I think there is much more truth to the second paragraph of the Shema (and that is to whom it's directed; the pronouns are second-person plural). What's more, while most Jews are no longer farmers in the narrow sense, ALL Jews and the whole human race still take part in the great flow of rain, sun, earth, seed, which make up the rhythms of earth. And those rhythms are (a) crucial; (b) in crisis; and (c) responsive to human behavior.
I read the second paragraph as saying: If you listen, REALLY listen to the teachings of YHWH, the Breath of Life, especially the teaching that there is Unity in the world and interconnection among all its parts, then the rains will fall as they should, the rivers will run, the heavens will smile, and the good earth will feed you. BUT if you shatter the harmony of life, if you chop the world up into parts and choose one or a few to worship--like gods of wealth and power, greed, the addiction to do and make and produce, without pausing to be and make Shabbos--then Breath of Life will come as a hurricane to shatter your harmony. The rain won't fall (or, it will turn to acid), the rivers won't run (or, they will overflow because you have left no earth where the rain can soak in), and the heavens themselves will become your enemy (the ozone layer will cease shielding you, the carbon dioxide you pour into the air will scorch your planet), and you will perish from the good earth that the Breath of Life gives to you.
So, therefore, set these words/deeds in your heart and in every breath, carry them in every act toward which you put your hands, and make them the pattern through which you see the world. Teach them to your children, to repeat them to their children; stay aware of them when you sit in your houses, when you walk on your roads, when you lie down, and when you rise up. Write them on the thresholds where you cross from world to world, to door posts of your houses, and your city gates.
