expand_less As World War II came to an end, Reghini intensified his work on Pythagorean numbers. Perhaps sensing that his time was short, he left detailed instructions concerning his manuscripts. [33] At five o'clock on the hot afternoon of July 1, 1946, in a country villa near Bologna, he died standing in his study, facing the westering sun.
In one of his later works on the relationship between mathematics and the spiritual quest, Reghini stressed that true philosophy involved the direct experience of the seeker:

Modern Western science is objective experimental science, achieved externally by instruments which aid the senses; its purpose is to observe, understand, taking into account the inevitable alteration (the Heisenberg principle) made on the observed conditions by the observer. In Masonry, Hermeticism, Pythagoreanism, and esoteric science of all times, the observer is also the object of the experience, considered internally and directly without limiting the field to any imaginary columns of Hercules; not so much a matter of theorizing as of feeling and living. [34]

And what indeed is the purpose of philosophy—the love of wisdom—if not, as the Neoplatonist Porphyry said, "to free our mind from limitations and chains"? [35]
