The most consistent and visible facet of the Big L is probably mother love. It meets the tests admirably, although it often gets heavily layered with protocol.
Men find the Big L in other men and women in other women usually as a result of profound experience over some time, although extended experience does not automatically evoke the Big L. Yet when it does happen, sometimes effortlessly and without conscious awareness, it is permanent in the full meaning of the word. If you work together, play together, live together, fight, suffer, laugh, and team together, the probability is increased.
The main characteristic of the Big L is that it does not diminish with physical death and you cannot extinguish it during physical life. Out of necessity, propriety, or for reasons beyond your control you may sublimate it, yet it will always be there, glowing quietly within you. Why the expression “till death do us part” became part of our culture is a mystery. Perhaps it was inserted so that the physical survivor would feel emotionally free to remarry and beget more offspring to further ensure the continuation of the species. Otherwise it makes no sense.
