I mean, I got pointing out instruction by CNNR and others, and have the precious vase standing here, but would never consider doing those practice in a session without my teacher telling me to.
Otherwise, it's just playing around with some gimmick that we're not ready for anyway. Isn't it?
No it isn't. You're just being a little silly.
Rinpoche has explicitly said multiple times that after we have received a direct introduction we can freely do all the semdzin and rushan (and also zernga) and they are explained well in various books so we can read and apply. You don't need
any special blessing or transmission or permission to do them. Of course I'm talking about how it is with Chogyal Namkhai Norbu Rinpoche, I don't know if everyone teaches this way. If your root teacher isn't Rinpoche and he says otherwise then probably better you listen to him.

Well the explanation on semdzins is in theg mchog mdzod, I don't think it has a particular title. Otherwise the semdzins are mentioned in Dra Thalgyur and Nyida Khajor (apparently in this one also described) tantras. But if you meant which book it is in the DC, it's just called "The 21 Semdzins of Dzogchen Upadesha", it has the translation of Longchenpa's text and Rinpoche's oral commentary.
Tun in DC is 2 hours (minimum).
