By 6. If you simply can’t do something, explain why.
I’ve had to stop priests in animist religions from bringing in live animals, and gently tell Native American families that they can’t burn sage in a hospital room. There are certain rules that you can’t break, like having live fire in a room with oxygen in the wall. If you run into that situation, explain, explain—and do it with respect for the importance of the person’s beliefs. I may not be able to let you burn sage (or incense) in your room, but I can agree to open windows or doors at certain times if that’s what you need to make sure your soul gets free in case you die.
As a boring Midwestern Methodist, I’m most grateful for the part of my job that allows me to see and learn about different religious and cultural traditions. Not only has it given me the taste for really spicy Ethiopian and Indian food, it’s provided me with the thrill that only an elevator full of monks in saffron robes can bring. Take the time to ask, to be curious and sensitive about your patients’ needs, and you’ll surely learn something. You might also get the experience of a lifetime when the monks show up to chant.
