Question: You explained that through a connection between two, a third completely new thing is born, and those two things disappear. But why doesn’t this happen in our world? A father and mother produce a child together, but they continue to live along with the child.
Answer: Connection is not a link between physical bodies but a union of desires. The physical bodies don’t connect because it is possible to take gametes from a father and mother and make a child in vitro.
But this is not called connection; connection happens with desires. Each one works with his desire, and then from two opposite desires, a third is born that includes both of them within it.
Connection is a shared existence of both desires on a higher level. Concession and nullification of the self within the connection doesn’t cause harm, rather the opposite, it adds fulfillment and makes it possible to rise even higher.
The desire to receive itself doesn’t ever disappear; this is the substance of creation. In the meantime, we temporarily nullify those desires that cannot be used for the sake of bestowal. With the desires that can be used in order to bestow, we combine in such a way that they create a third body called Adam (man/human), which includes both male and female within it.
