Chokmah-Chesed
The wisdom that exclusively one attains is not for oneself.
The wise must be wise to bestow mercy and, if he is truly wise, he must know that he also needs the energy of mercy for his own "I".
The expansive energy of Chokmah descends to the expansive energy of Chesed. We know that the energy of Chesed is of a lower level, that is, it is more contracted.
We attain wisdom when we understand that the root of good and evil is the same. The wise man knows this secret.
This is the key difference: the mercy of Chesed must not fall into the naivety of believing that a merciful one does not know evil.
It is precisely the energy that descends from wisdom (Chokmah) that teaches us to be merciful despite the attacks of evil.
Evil should not transform us into mercilessness; in that case, we are not really wise.
Wisdom sends important information to mercy. You must learn to be merciful in spite of the attacks of evil, because from evil you learn.
You attain true wisdom if you know and know how evil works.
One must be merciful: if you are not merciful, you cannot access wisdom. Of course, mercy always understood as a way with oneself and with others.

Chesed-Chokmah
When the energy of mercy ascends towards wisdom we meet the energy of forgiveness.
I must forgive myself and others.
Forgiveness does not cancel my responsibility for my existence and the existence of the universe.
If I am merciful to myself and others, I must in turn have the humility to forgive myself in order to move forward.
We cannot burden ourselves with guilt, which only interferes with our life plan. How long will we recriminate ourselves for what we did not do or what we did wrong? This shows a lack of emunah (of trust in everything, as it should be according to divine will).
I can review my actions, of course, but I cannot live the rest of my existence blaming myself for things that should have gone differently. We must move on.
The Chesed forgives me so that I do not remain stagnant and continue to rise towards the light of the Chokmah. There are no excuses for slowing down the growth towards the light. I forgive myself and move forward.
The wise is one who forgives himself in his just measure, without nullifying his responsibility with his rectification process.
