Nature itself provides no proof of the need for human connection. We can identify various examples of such a need for survival purposes, but there is no proof of such a need in nature itself.
In our lives, we reach various forms of connection other than a human-to-human connection that is felt at the level of our emotions. In such a place, we need to bring ourselves to connect against our egoistic desire that constantly pulls in the opposite direction, i.e., which aims at self-benefit over benefiting others, and using any kind of connection not for the benefit of everyone, but for the benefit of an individual or a group that benefits that individual.
Only by connecting above the ego can we reach a harmonious connection, as it is written, “as one man with one heart.”
However, human-to-human connection does not happen naturally and instinctively, as it does in nature’s other degrees: the still, vegetative and animate.
Specifically, connection is unique to the human level in that we resist and oppose each other according to our nature, as we can see throughout history, and that in order to truly connect, we need to rise above our egoistic nature.
