[Disclaimer: the following is pure speculation and a collection of observation. Do not take this as fact.]
We’ve seen BTS in blindfolds and ropes particularly Blood Sweat and Tears and Jimin’s Lie. Here we will delve into the masonic initiation using those methods:
Hoodwink (blindfold) the candidate and ceremonially tie ropes around him—though the form of the tying varies.
Lead the candidate blindfolded in a circumambulation (walking around) of the temple.
Jimin in BST
Jimin in Boy Meets Evil
Both cause the candidate to endure (while being blindfolded) being picked up, spun around, carried around, being jostled or struck from person to person. This is supposed to produce an “altered state of consciousness.”
