Just out of curiosity, here are sixteen off-beat, crazy questions about what an enlightened person might do. Feel free to explain your answers because that might start a discussion.
I'll give this a shot, but not from the Vedantic perspective, but rather from a traditional and orthodox school. The definition of enlightenment would be nirvikalpa samadhi, or in English, Self-realisation. In orthodox schools, it is beyond time,form, and space, and can only be 'obtained' through intense meditation and celibacy, whereby all karmas are burned. A Guru is an absolute must to attain this state. This differs substantially from previous definitions here.
(1) Do you think an enlightened person would likely express contempt for people who were behaving foolishly?
Never. They would understand it as a stage all souls go through.
(2) Does it make sense to you that an enlightened person would likely tell people he or she was enlightened?
Never. That's an endorsement others would notice, and put on the individual.
(3) If an enlightened person saw a bit of trash on the sidewalk, and was not pressed for time, would he or she likely pick it up to throw in the trash bin? What's your best guess?
Probably, if they noticed.
(4) If you happened to be speaking to an enlightened person, do you think he or she would likely pay unusually close attention to what you were saying?
Absolutely, and if the degree of accompanying siddhis was highly developed, you wouldn't even have to verbalise the question. This would only happen if the enlightened person was in a relaxed mood, as most take great pains to hide such things.
(5) Would an enlightened person likely make casual or idle comparisons between one person and another?
Never, unless it was useful to a student, or disciple. It would be rare.
(6) Would an enlightened person likely make you feel he or she thought you were unique or special?
Definitely.
(7) Would an enlightened person likely be curious about you?
Yes, but not in a normal sort of way. They'd be looking at your soul, not the ego/small I you.
(8) Would an enlightened person's home likely be clean and tidy?
It might be a cave, or no home at all, as said being could be a wanderer. The home would be simple, if it was in an ashram or mutt, it would be a very basic room.
(9) Do you think an enlightened person would usually or habitually eat his or her food with condiments?
It wouldn't matter. Sometimes. Sometimes not. Food wouldn't be much of a concern. They could easily skip meals, for instance, might not even notice.
(10) Would an enlightened person likely jump or start if you made a sudden noise behind him or her?
Probably not, but it might depend on where they were functioning at that moment. It can be dangerous to awaken someone from deep samadhi.
(11) Would an enlightened person likely notice if he or she were in a large room and a door was very quietly opened at the far end of the room?
Yes.
(12) Would an enlightened person likely be bored?
Never, Apparently the inside is quite exciting. I've heard it compared to walking a tightrope.
(13) Would an enlightened person likely masturbate?
Never, as per my definition. Well beyond base instincts.
(14) If an enlightened person thanked you for complimenting them would they likely thank you because the compliment was important to them or because it was important to you?
Neither generally, but perhaps. Generally enlightened people have tact and are polite, but there would be no attachment to it.
(15) Would an enlightened person likely be curious about the fact that only one of these questions explicitly asks the reader to make a guess?
No.
(16) Would an enlightened person likely idealize enlightened people?
They would recognise one, and acknowledge and respect their own teacher.
Have fun! And please don't take these questions too seriously!
