The saying “I have created the evil inclination, I have created the Torah as a spice” expresses the whole thought of creation. The goal of creation is to bring everyone to a perfect connection called love, and so love of others is the main idea and goal of the Torah.
The Creator continuously develops people’s egoism so that they will recognize and understand the need for unity. First they will have to connect in order to survive and then in order to reach a more sublime meaning.
The wisdom of Kabbalah disappeared from our world for 2,000 years in order to allow the ego to develop and so that we would have something to correct. Kabbalists predicted that since the end of the 20th century in the year 1985, we will reach the right level of the ego needed for correction.
“Love thy friend as thyself” refers to a connection with others in which everyone mutually fills others. This means that the meaning of the word “love” is not bringing others pleasure but filling the upper desires of others. In that case love evokes the full connection between all of humanity into one system called Adam (man).
