Anything of importance is not a choice. Choices are trivial. What this means is that, at a deep level, nothing is voluntary. This is why it is impossible to learn by copying externals. The master does something because he has to – because with an act of spirit he has ordered his mind and energy in such a way that he has no choice but to do what's done. If you merely copy externals then you will never get to the spiritual source of that movement. To get there you will need to copy the total life that's lived by the master, and to learn this takes decades of dedicated practice, and even then there are no guarantees.
