Given you'll probably spend most of your time in a robe and slippers, you won't need to bring a lot. Besides comfy clothes to change into after your massage and spa treatments, essential items such as underwear and deodorant should be on your packing list. Of course, if you intend to make use of the resort's pool or engage in exercise sessions, throw a swimsuit and some gym attire into your bag too. Finally, leave the electronic devices behind and bring a magazine instead. It is, after all, an escape from the real world.
