The San Francisco Zen Center, which has emerged as one of the largest Buddhist sanghas (communities) outside of Asia since its founding, is celebrating turning 50. Monday's events, featuring a procession, formal ceremony and reception, attracted Lisa Kee-Hamasaki, above, coming out of the Sokoji Temple on Laguna Street; Annie Hallatt, center right, sporting a colorful costume of the Buddha during a procession from the temple to the City Center; and Anna Malo exhibiting the spirit of the day at Buddha Hall after the procession.
