What is an appropriate expression of sympathy for a Sikh family whose mother recently passed away?
You could get in touch with their church (or whatever it’s called) and ask someone what would be an appropriate way to express your sympathy. In our culture, going to the funeral home, writing a formal letter of condolence, and bringing food to their home are some of the ways to do so. However, they may have dietary customs you don’t know about, or other specific customs, such as which colors of clothes to wear when visiting. So find out, and then do as your heart prompts.
