There's something about the window between Rosh Hashanah and Yom Kippur that people feel - even if these holidays are not part of their culture and they do not celebrate them traditionally. It's just something in the energies of reality experienced at this transitional time of the year. For some this is the beginning of a new year rather than on the January 1 date.
Growing up in a predominantly Jewish area of Brooklyn, my family honored the traditions of the holiday. As I became an adult, I could still feel the energies but didn't follow the traditions. My children still remember that their father used to take them to Temple on these high holy days as these holidays meant a lot to him. Today only one of my three daughters goes to temple and follows tradition.
Like everything else, religion is a personal experience that one may chose to embrace as they go through the different chapters of their lives. Some people find religion as they get older, while others move away from it. In my years of metaphysics I have found that people believe in a spiritual origin - not so much in the paradigms of tradition.
Today we celebrate Yom Kippur. Some people will fast and others will not. Some will go to temple well others will honor the holiday at home either alone, with family, or with friends. Happy New Year to those celebrating one way or another. As we live in rapidly changing times - this year will bring interesting changes to our lives and the world.
