A lot of teachers of meditation are experts in one tradition. The challenge is that, as a society, we've started to believe in experts. You can go to wherever you want to and they'll teach you their technique. Everyone struggles with this. It's a normal part of the meditative process. If your student is having a problem, if the student is struggling, that’s a fault of the teacher, not a faults of the student. This has been completely lost in meditation instruction.
