Panulame miwah iluminasi ngalimbakang pengalaman-pengalaman sajroning pikayun miwah parilaksana sane nenten manut sasana, asapunika taler panulame saking indik-indik sane kacingak tur kapirengang, prasida kauningin utawi katarka saking makudang-kudang pamargi, tios ring baga 'diagnosis psikiatri barat'.[example 1]
Shadows and Illuminations explores how non-normative mental events and behavior, including auditory and visual hallucinations, can be understood or interpreted in multiple ways outside the confines of Western psychiatric diagnostics.
"In a culture where no distinction is made between the secular and the religious or supernatural, the sekala and the niskala as the Balinese call them, the latter can enter into daily routines and beliefs ...Sekala means what you can sense -- see, hear, smell, and touch. Niskala involves that which cannot be sensed directly, but which can only be felt within. Niskala plays a much more important role in Balinese culture than it does in the West. Niskala is a very personal matter, often difficult to articulate or, in some cases, hazardous to do."
