I have posted elsewhere about the value of numerology in understanding so-called mental illness. I believe that numerology is an insightful way of relating to people who are in a mental health crisis. Ancient mathematicians, like Pythagorus, imputed meaning to numbers, based on vibrations and planetary movements. People experiencing schizophrenia see meaning and connections that are not apparent to others. Jung called this synchronicity.
My son, Chris, is quite interested in how numerology has relevance to his life. A few months ago I gave him a book on numerology for his birthday which he studies from time to time. This enables us to have interesting discussions about his personal growth and perhaps an eventual career path. These discussions are much less intrusive than "Well, son, when are you going to be ready to take on a full time job or studies?"
Example: Chris is becoming much more socially outgoing. Sure enough, he is in a personal year 3, the year of becoming more outgoing. He is really opening up to me with his personal thoughts and reflections. This is not something that he did as a child. I am seeing a reconstructed personality emerging.
In numerology, there are nine year cycles. To understand where you are with respect to that cycle, you take your date and month and the current year, and reduce the numbers down to a prime number (11s and 22s being the exception.)
For example, if tomorrow (3)/(5) is your birthday, and you were born in 1965, you are on year three of the nine year cycle.
3 prime number
5 prime number
Out of curiosity, and based on Chris's numbers, I revisited the time when in hindsight Chris's troubles were beginning to surface, to the present day. In 1999 he ended a nine year cycle and began a new one. What I recollect from that year concerning his health is that he began to experience very bad acne. (Dr. Abram Hoffer says that severe acne at this age is often a precursor to schizophrenia. It is a pellagra like condition related to a lack of B3 or niacin.)
Both Chris and I agree that his most recent hospitalization in 2008 marked the end of his nine year cycle and the beginning of his new nine year cycle. Since leaving the hospital, he has taken baby steps towards discerning his life path by taking a course here, a small job there. He is currently working ten hours a week helping an artist with his projects and tending the artist's garden.
I find that the numerology perspective helps me to be patient, to see that life is change, growth, and there is a time for everything.
