“Rabbi Shim’on son of El’azar says: Greater is he who acts from love than he who acts from fear, because with the latter [the merit] remains effective for a thousand generations but with the former it remains effective for two thousand generations. Here it is written: And doing kindness to אֲלָפִים (alafim), thousands, for those that love Me and who keep My commands (Exodus 20:5) and elsewhere it is written: And keeping His commands to the אֶלֶף (elef), thousandth, generation (Deuteronomy 7:9). But in this latter passage it is likewise written: For those who love Him and keeping His commands to the thousandth generation!—in the first verse cited [thousands] is attached [to for those that that love Me,] whereas in the second verse [thousandth] is attached [to keeping His commands. So in the former the motive is love, in the latter fear of punishment]” (BT Sotah 31a).
“Rabbi Yehudah, son of Rabbi Shim’on, expounded: He who blackens his face for the sake of Torah study in this world, the blessed Holy One will make his lustre shine in the next, as is written: Like Lebanon he is choice as the cedars (Song of Songs 5:15) [לְּבָנוֹן (Levanon), Lebanon, is cognate with לָבָן (lavan), white]. Rabbi Tanḥuma son of Rabbi said: He who starves himself for the sake of Torah study in this world, the blessed Holy One will fully satisfy him in the next, as is written: They take their fill from the fare of Your house and from Your stream of delights You give them drink (Psalms 36:9).
When Rabbi Dimi came, he said: The blessed Holy One will give every righteous man His heap [of reward], for it is written: Blessed be the Master day after day. God heaps upon us our rescue. Selah (Psalms 68:20). Abayye demurred: But is it possible to say so? Is it not written: Who has measured the waters in the hollow of His hand, and measured out heaven with the span? [how then can man receive such a vast reward?] (Isaiah 40:12)—he replied, ‘Why are you not found familiar with the aggadah [the nonlegal contents of the Talmud and Midrash]?’ For it was said in the West, [i.e., the Land of Israel] in the name of Rabbah son of Mari: The blessed Holy One will give to every righteous person three hundred and ten worlds, as is written, So I may endow those who love Me with substance and fill their treasuries (Proverbs 8:21)—now the numerical value ofׁ יש (yesh), substance, is 310 [thus man’s receptive capacity will be enormously increased]” (BT Sanhedrin 100a, cf. M Uqtzin 3:12).
“[Son of Rav Safra] opened, saying, ‘For a mitsvah is a lamp and Torah is light, and reproofs of discipline are the way to life (Proverbs 6:23). For mitsvah is a lamp—Mishnah, as is said: the Torah and the mitsvah (Exodus 24:12); the Torah is Written Torah, and the mitsvah is Mishnah, which is a lamp, a lamp ready to be kindled.
A lamp—why is She called a lamp? When She receives, between two arms, 248 supernal members, and She opens Her two arms toward them, then those two arms are included with them and She is called נֵר (ner), lamp [numerically equivalent to 250].
And Torah is light—illumining that lamp, which is kindled by it from the side of primordial light, as is written: from His right hand, a fiery law for them (Deuteronomy 33:2)—given from the right side, although the left was included in it, for thus is perfection of all.
This light is absorbed by 207 worlds, which are hidden away on the side of that light, and it spreads through them all. Beneath the supernal concealed Throne dwell those worlds on that right side. There are 310: 207 on the right side and 103 on the left side, totalling 310. These are the ones that the blessed Holy One constantly prepares, and from these spread countless precious treasures all stored away for delighting the righteous in the world that is coming. Of these is written So I may endow those who love Me with יֵשׁ (yesh), substance, and fill their treasuries (Proverbs 8:21). Of these is written No eye has seen, O God, but You, what You will do for one who awaits You (Isaiah 64:3).
יֵשׁ (Yesh), substance—310 worlds treasured away beneath the World that is Coming. אוֹר (Or), light, primordial light, is named after those 207 on the right side, because even light of the left is called light, but primordial light is destined to generate offspring in the world that is coming. Now, you might say, ‘In the World that is Coming, and no more!’ But even every single day, because if not for this light, the world could not exist, as is written: I declare, ‘The world is built by חֶסֶד (ḥesed), love (Psalms 89:3).
This light was sown by the blessed Holy One in the garden of His delight, and He arranged it in rows by the hand of the Righteous One, who is the gardener of the Garden. He took this light and sowed it as seed of truth, arranging it row by row in the Garden, and it sprouted and grew and yielded fruit, by which the world is nourished, as is written: Light is sown for the righteous… (Psalms 97:11)” (Zohar 2:166b).
“What is יֵשׁ (yesh), substance? חָכְמָה מֵאַיִן (Ḥokhmah me-Ayin), Wisdom from Nothing (Job 28:12). For in the place of the upper Shekhinah [Binah] there is Ḥokhmah, as is said: So I may endow those who love Me with yesh, substance, and fill their treasuries (Proverbs 8:21); And doing kindness to the thousandth generation for those who love Me and for those who keep My commands (Exodus 20:5)—from the side of Ḥesed, Kindness, and this substance, which is Ḥokhmah, Wisdom, is on the right as has been taught: One who desires to become wise should turn to the south [which is at the right hand of one facing the east] (BT Bava Batra 25b). And that is why it is written: So I may endow those who love Me with yesh, substance, and fill their treasuries (Proverbs 8:21)” (Zohar 3:238b, Ra’aya Meheimna Pineḥas).
