Хасидус к Берешит 2:17

וּמֵעֵ֗ץ הַדַּ֙עַת֙ ט֣וֹב וָרָ֔ע לֹ֥א תֹאכַ֖ל מִמֶּ֑נּוּ כִּ֗י בְּי֛וֹם אֲכָלְךָ֥ מִמֶּ֖נּוּ מ֥וֹת תָּמֽוּת׃

Но не ешь [плодов] дерева познания добра и зла, ибо в день, когда ты вкусишь от него, умрешь”.

And it appears to me that the root of the issue is this, that the Blessed Holy One of Blessing said "from all the trees of the garden you shall eat, yea, eat" (Genesis 2:16) - a hint to Torah, which is the tree of life, "eat" is an expression of hidden, the explanation is that this is learning for its own sake which is the root and the essence, as the Blessed Holy One of Blessing warned about, and at any instance, if you have not yet reached [the level of] Torah learning for its own sake, in any instance "you will eat", meaning, for your benefit [is] learning not for its own sake, and this is "you will eat": be present, and do not depart from My Torah. "And from the tree of good and bad you shall not eat from it" specifically, meaning, the physical things are in them - the mixture is also good, which are the holy sparks that are in every physical thing; "shall not eat from it", the explanation is that your intention should not be exclusively from the material and physical sides only, rather only from the spiritual side, in which the holy sparks are, from that you shall eat. "Because from the day you eat from it you shall surely die מות תמות" (Genesis 2:17) - mot tamut meaning, "die-mot" in the next world, the eternal life, and the expression "die - mot" is also hidden, a hint to the next world, the eternal life, [and] "die - tamut" in this world.

Likutei Halakhot

And this corresponds to Rosh Hashanah, to the blowing of the shofar, which is the aspect of arousal from sleep. As is brought in the Kabbalistic texts, Rosh Hashanah corresponds to sleep, and the shofar representes arousal from sleep, since, "The whole world was created in Tishri" (Rosh Hashanah 10b). This is the aspect of disorder, Tav-Shin-Resh-Kuf, and when disorder is aroused, you must submerge yourself completely in sleep, which corresponds to the sleep of night. Rosh Hashanah is the first day of the Ten Days of Repentance, and the essence of repentance is to repent from haughtiness, humbling oneself and truly sensing one's lowliness and unworthiness. As our Sages said, "One self-chastisement is greater than one hundred floggings" (Berachot 7a), and, "He forgives transgression for the remainder" (Micah 7:18) - "to the one who makes himself a remainder" (Rosh Hashanah 17b). Therefore the essence of repentance is humility and humbleness, for all sins arise from disorder, from separating the Malchut and possessing it with haughtiness. That is the source of all judgments, to which the evil inclination and the forces of evil are attached, from which all sins arise. The holy books speak about haughtiness being the cause of all sins, since, "Whoever is haughty is as if he worshiped idols" (Sotah 4b), and, "Whoever acknowledges idolatry is as if he denied the entire Torah" (Chullin 5a). We find, all sins come through haughtiness, G-d forbid, for haughtiness separates disorder from order, which is the cause of all sins. Therefore, the essence of repentance for all sins is humbleness, making yourself as dust to be tread upon, sensing your lowliness and distance from Hashem, lowering yourself and breaking your heart before Hashem. That is how G-d will forgive a person, as written, "G-d will not scorn a broken and oppressed heart" (Ps. 51:19), and "Who forgives transgression for a remainder" - "for one who makes himself as a remainder". This is because humility and humbleness, one makes himself as Mah, as nothing and naught. In this way, one returns to order, represented by Mah, through which all judgments, which correspond to sins, disappear. Therefore, on Rosh Hashanah, which is the first day of the Ten Days of Repentance, the first day of Adam's creation, we must "sleep" - we must completely submerge ourselves as if we have no knowledge at all, but only cry out to G-d and declare Him King, in complete sincerity, without sophistication. On Rosh Hashanah Adam and Eve were created, corresponding to order and disorder. It was their task to rectify all the worlds, representing disorder, into order, to bring 'Eve' into 'Adam'. Had they done that, everything would have been brought into order, without any suffering and judgments, which represent disorder. But they blemished with their sin, and in doing so, they separated disorder from order, for their main sin was haughtiness, 'I shall rule', which was the essence of the Primordial Serpent's enticement, as written, "For G-d knows that on the day you eat of it, your eyes will be open and you shall be like G-d" (Gen. 3:5). As our Sages said, "It told them, 'Every craftsman hates his fellow craftsman - G-d ate from this tree and created all the worlds'" (Genesis Rabbah 19:4). In other words, he aroused jealousy in them and a desire to rule: 'you shall be like G-d' - 'creators of worlds', as if to say, 'Why should you subdue yourselves to Him? If you eat from the Tree of Knowledge, you will be a Gd and a King just like Him!' All this is the aspect of 'I shall rule', in that one desires to draw Malchut/Kingship to oneself, and then everything gets in disorder, for the person himself is in disorder. That is why all generations of mankind became destined to die, for they had blemished order, corresponding to wisdom, the source of all sustenance, as in, "Wisdom sustains life" (Kohelet 7:12), as in, "Mah is our life?". With their blemish, they separated themselves from order, from wisdom, from Mah, the main source of sustenance, and death as opposed to life was the inevitable result. Their blemish also caused everything to become disordered, represented by all the blemishes and decrees that were a result of their sin, as written, "With toil you shall eat of it...thorn and thistle will grow for you" (Gen. 3:17-18), upon which Rashi comments, "When you plant wheat, the earth will give forth thorn and thistle". All this corresponds to the disorder they caused with their sin, which was haughtiness, 'I shall rule', which caused all things to become disordered, since they had evoked disorder upon themselves with their sin. Not only did they not rectify, elevate and refine the world of the judgments that are attached to disorder, bringing everything into order, which is what they were supposed to do on the day they were created - for elevating the entire world to its source, merging disorder into order, was the very purpose for which Adam and Eve were created - but they caused great damage with their sin. The serpent first entices Eve, since she represents disorder, from which the forces of evil derive their power. The rectification should have been by merging disorder into order, by Eve being subservient to Adam, but the serpent overpowered Eve, representing disorder, enticing her to separate 'Eve' from 'Adam', disorder from order, so that Adam would follow Eve's will, so that disorder would rule over order. But they immediately repented and began rectifying everything, a rectification that would not be completed until the coming of the Messiah.

Shem MiShmuel

But about the fruit of the tree in the middle of the garden that God said, "You shall not eat of it or touch it, lest you die" (Genesis 3:3): And in Rashi (Rashi on Genesis 3:3): She added to God’s command (which did not forbid touching the tree, but only eating of its fruit); therefore, she was led to diminish from it. It is to this that Solomon says: Do not add unto His words (Proverbs 30:6). But this must be understood. Is it not our obligation, and is it not proper for us to do this, and were we not commanded about it to make a protection for the protection? So she did well to add [the prohibition of] touching so that she would not come to eating. And the law is like this with chametz (leavened grains) in the Talmud (Pesachim 1ob). [There] Rabbi Yehudah made a decree and negated the commandment to search and destroy chametz [if one finds it] during the holiday, lest one come to eating from it since people are not used to separating from it year-round. And [even with] the rabbis who do not make the decree, it is because that he is looking for it to burn it [at this time, so he will not come to eat it]. And Rabbi Meir (Pesachim 11a) also makes the decree even when people do separate from it, such as with the new grain. See there. And, if so, what sin did she sin when she added to the command? And in fact, [it is written] in Avot DeRabbi Natan 1:5 about that which the men of the Great Assembly said (Avot 1:1), "Make a fence for the Torah": And create a fence around your words just as the Holy One, Blessed be He, created a fence around His, and the First Man made a fence around his, etc. What safeguard did First Man make for his words? The verse states, etc. from the tree of knowledge [...] you may not eat, etc. (Genesis 2:17). First Man did not want to tell this to Eve in the same manner that the Holy One, Blessed be He, had told it to him. Rather he told her thus, making a safeguard for his words, [restrictive] to a greater extent than what the Holy One, Blessed be He, told him: But about the fruit of the tree in the middle of the garden God said, "You shall not eat of it or touch it, lest you die." — because he wanted to guard himself and Eve from the tree, not even to touch. To here are [its words]. It pushes it to say that [the excerpt in Pesachim and Pirkei DeRabbi Natan] are midrashim that disagree. And, regardless, the mishnah in Avot presents a difficulty for Rashi. And it is also difficult in the opposite direction from the verse that Solomon said: Do not add unto His words.
