"When two people fall in love, their immune systems make a contract to suspend their function." — Amit Goswami.
The words above from an expert in quantum physics are among the most poetic and powerful descriptions of love I have ever read.
The main task of an immune system is to protect a system by discerning between what is part of that system and what is not. Thus, the immune system recognizes and stops potential harmful invaders from entering the system and causing damage. In the case of our body, the immune system recognizes and stops things like bacteria, viruses and parasites.
Our immune system is not just a physical defence mechanism; it also plays a crucial role in maintaining the balance of our lives. Psychologists Robert Kegan and Lisa Lahey have found that it constantly evaluates and prevents any changes that could disrupt this balance, acting as an immunity system that immediately stops any infectious change and restores the status quo.
The same thing happens with people. When you meet someone, your immune system gets to work. This person is not me, so let's activate all the defences. The level of defence your immune system activates depends on many factors, but it's always ready for battle.
However, when you are in love with someone, your immune system suspends its function of distinguishing you from someone else who is not you. You experience a profound sense of unity, a state of being that is love and dissolves any separation between you and the other person. As Rupert Spira writes, "This dissolution of separation is known at the human level as love in relation to others and beauty in relation to objects."
"Fear prevents us from love." — Amit Goswami.
