This kind of teaching is very didactic and can be very specialized instructions for a specific practice with a set target. Serious meditation practitioners receive such instructions before and while they embark on long processes of meditation. Instructions are given to a small group or to a single disciple. One-to-one instructons are sometimes oral and very private in nature as the master guides the students step by step in a close supervision. However, some trhi instructions in Bhutan are given to large crowds as a public event, especially by the Je Khenpo or Chief Abbot of the State Monk Body.
