What does the source say about the reason Maharaj kept four lamps lit while sleeping on the suspended plank?

The source text from Chapter 0 provides specific details about Maharaj's sleeping habits during a particular time. It mentions that after a devotee brought him a wooden plank, he hung it from the Masjid's rafters and slept on it. The text explicitly states, "While sleeping, Maharaj would place four lit lamps at the four corners." However, the source does not offer any explanation or reason as to why he did this. It only documents the action itself as part of the description of this curious sleeping arrangement, which eventually had to be stopped because it was attracting too much attention.
