A little detail you might have missed at 2:17 - 2:20, there were two beams at the Supreme Kai planet. That being because as Beerus said later, he made some precautions as he was making his way to Earth by sealing away Kibito Kai so in the chance that BVB attempted to kill him, he'd have no idea where to find him, even if he knew Shin's ki signature.
@@SSJBELIactually ki in db is made up of three elements and one of them is related to mental and emotions . That's the thing which gives ki user mental resistance against telepaths and also helps them do telepathy and it also helps them control their ki . So beerus or any hermit can read minds only if opponent is weaker or less master in ki then you.
