Only an awakened (who sees how dream is and remains undistracted) can see sharply what miperception/how misperception in a students' nature is by examinating this. This is probably the base of what is needful. In groups, I don't know. Also many masters also are rime. Yongye Mingyur La, great teacher his only concern is "to help nature see nature".
Then careful seeks how to introduce nature depend on this. Then there is not a question in why combining or merely nature recognizing but to use what is waking up in pure honesty, unconditioned love and skills at that moment.
To remain stable master can give you extra practices, one must be sincere, and able to remain in trust, and secrecy, respect what is sacred.
Ask it a Dzogchen-Mahamudra master, friend in Africa, in all honesty. Even the sharings here can be general info for all of us, no any master is going to tell you: ask it on internet.
“Sentient beings, self and others, enemies and dear ones—all are made by thoughts. It is like seeing a rope and mistaking it for a snake. When we think that the rope is a snake, we are scared, but once we see that we are looking at a rope, our fear dissipates. We have been deluded by our thoughts. Likewise, mentally fabricating self and others, we generate attachment and aversion.” ~Dilgo Khyentse Rinpoche
