My Comment: In corporeal relationships, love is based on instincts, on hormones. However, in Kabbalah mutual concessions, mutual attraction to each other, mutual help, and mutual care are called love. In principle, love is a state when you feel the desires of the other and fulfill them.
Question: Does it mean that I am a tool for fulfilling the other?
Answer: Yes. In this case, we can say that you love him or her.
Remark: You once said that the unit for measuring love is the unit of sacrifice.
My Comment: Yes. It is the extent to which you sacrifice yourself, that is, your diligence, your efforts in order to fulfill the other.
Question: If love is built on mutual concessions, then who should concede? Both of us? If I concede, the other will take advantage of me and vice versa. How to choose a measure here?
Answer: In this case, a joint contract is drawn between two extremely opposite parties that enter into a covenant with each other and undertake to help each other in revealing the Creator between them. This must be taught, learned, and nurtured.
