It is still necessary to understand the very root of the matter: How is it possible for there to be an intermediary that includes within itself an entity and its diametric opposite, a tendency and its very antithesis? [The interrelation of the qualities of] Chessed and Gevurah expressed in our intellectual and emotional faculties, [as well as] in the animal kingdom, in the plant kingdom, and in [the elements of] fire and water and the like, [appears to be a logical anomaly].
[In resolution,] we are forced to say that the qualities of Chessed and Gevurah [as we know them] do not exist in their simple, elemental state where they are two opposites, but rather as composites. To explain: The difference between an entity as it exists in its simple, elemental state and its existence as a composite is well known. As it exists in its simple, elemental state, it cannot bear any opposing or conflicting quality. When, by contrast, it exists as a composite, it can bear its opposite.1 For example, fire and water [in this world] do not exist in a simple, elemental state without being compounded with each other. For were that to be the case, it would not be possible to combine them in an intermediary at all. Instead, fire has a dimension of the aspects of the element of water and water has a dimension of the aspects of the element of fire,2 as is well known from the books of the natural scientists. And as stated in Sefer Yetzirah:3 “He extracted fire from water and water from fire.” This pattern is seen whenever there is a division into opposite tastes in the plant kingdom: sweet and bitter, sharp and soft. And healing herbs, [though bitter,] can give life to one who is dangerously ill, as explained above. For good exists within evil and evil exists within good. There is sweetness in bitterness and bitterness in sweetness. Similar concepts apply with regard to heat and cold.
Accordingly, it is possible that [opposing qualities] can be combined in an intermediary. This is expressed through the different blendings and combinations that are made with the particles of the four elements fire, wind, water, and earth, as is well known. Similar concepts also apply with regard to the possibility for synthesis that exists in the quality of truth that is referred to as beauty. As explained above, it blends the two opposites, Chessed and Gevurah,together. This is possible because those two qualities each contain [in a subtle manner] the opposite quality. For example, we see that within kindness, there is a dimension of the attribute of judgment.4 Thus one will requite his enemies with kindness to destroy them.5 And it is written:6 “If your enemy be hungry, give him bread to eat… for you shall heap coals of fire upon his head.”7 One is thus carrying out and enclothing a severe judgment in a garment of kindness.
Conversely, striking one’s son and causing him suffering [to motivate him] to improve his conduct reflects how kindness is enclothed within judgment, as is well known. (This is referred to as the Gevurah of Chessed or the Chessed of Gevurah.)
[Similar concepts apply regarding G‑d’s attributes.] Thus we see that the wicked may be granted prosperity. This is a reflection of the attribute of judgment being enclothed in kindness. They are granted [prosperity] for the little good that they do possess, so that it will be possible to destroy them utterly in the World to Come.8 Conversely, the righteous [may] suffer [in this world,] receiving punishment for the bad they possess, so that they will receive [unadulterated] benefit in the World to Come. This is an expression of hidden good that is enclothed in severe judgment that brings about suffering.
All of the above indicates that there is an intermingling of Chessed and Gevurah that allows for the existence of an intermediary, as explained above. This [form of intermingling, where an evil person will receive actual goodness and a good person will be subject to actual suffering in this world,] is a consequence of the intermingling of good and evil that came about because of the sin of Adam,9 the first man,10 who partook of [the fruit of] the Tree of Knowledge, as is well known. As a result, there is no good [in this world] that does not contain bad in it in a hidden state, nor is there bad without good in a hidden state.11 For this reason, “a person is obligated to recite a blessing over a [seemingly] unfavorable occurrence as he would recite a blessing over a favorable one.”12 For this [seemingly] unfavorable event contains actual good in a hidden state.
The refinement [of unfavorable occurrences and the revelation of their hidden good] is brought about by the qualities of mercy and truth, as explained above (sec. II) which are identified with knowledge and beauty.13 For without knowledge, there will be no distinction14 or clarification between what is good or bad or true or false. This represents the totality of the [mission and] task of a person who possesses perfect character traits and emotional qualities: that his mind and his emotions should be refined, following an intermediate path in a complete manner, as explained above.
