Zohar for All, Chayei Sarah, Item 74: All the deeds of wicked Balaam were from the side of impurity.
In the beginning of his deeds he took a serpent from among the serpents and tied it before him. He split the head of the serpent and took out its tongue. Then he took certain herbs and burned them all and made a single incense out of them. Then he took the head of that serpent and split it into four sides and turned it into a single incense (Item 77).
Making incense is making the most of your egoism.
Balaam is a property that pulls us to be so selfish that we do not even know what it is. Only as we climb the spiritual levels do we begin to feel it.
In fact, everything that is written in The Book of Zohar talks about people who are already spiritually ascending and feeling these problems.
Around it, he drew a single circle and would say things and do other deeds until he drew upon himself the spirits of impurity, which informed him what was needed. And he acted by their words, according to what they knew from the side of that serpent of the firmament (Item 78).
The task of Balaam is the same as that of the snake. All the negative characters in the Bible are intended only to continue the same work, that is, to come to a person at the right time and sting him with their egoism.
The fall of a person into egoism shakes him up. From this state, he begins to see a distant goal and to rush toward it. Therefore, he needs such a shaking, what is called the awareness of evil.
