After Trump's election, which feels so long ago, I advised friends to mourn but not despair, and instead take action to help those you think he'll endanger. I didn't have any practical advice on how to do that though.
Yesterday I joined the Board of the Theosophical Order of Service. It's a wonderful organization started by Annie Besant, with the motto, "A union of those who love in the service of all that suffers." My practical advice isn't to join a Board, but go join something. Join a group that's doing some good in your community. The Theosophical Order of Service (TOS) is one such organization that has local groups all over the country, but there are more than we realize.
