One major feature of discipleship is the hands-on one-to-one training with the master.
This is vital.
Hundreds of hours of training are required.
The student must literally 'feel' how the master moves, learn their secrets, their rhythm, their timing.
The physical is-ness of the art cannot be passed-on by words, by watching or by willpower.
It must be experienced through touch.
This process is beyond words.
