For a beginner, it is impossible to see the whole process
Even if the teacher use a clear way to explain,
The student still can't understand it
Only if the students follow the teacher for many years
Then he can know some processes
Don't you think that the student should learn immediately how to begin?
What's the use of seeing the whole process, if the teacher fails to explain how to begin?
But there is a problem
How can the student find a "true" teacher?
It is always a big problem
I've heard many stories of people meeting immortals that roam the wild mountains.
It's hard to find them, and even if you do, it's rare that they'll teach something.
Surely, you've heard of Li Ching-Yuen (李清雲).
He met various masters in the mountains and he learned and transmitted many of the arts that Bo-Duan labelled as "easy to find, but hard to succeed", including the MCO.
Buddha learned from two teachers
But he found the way by himself
Buddha had many students
Not each student find the way
Buddha was looking for the way to end suffering.
His two teachers taught him the way to enter deep trance states.
When he discovered that he could apply his trained powerful mind to continuously perceive the three characteristics of impermanence, no-self and un-satisfactoriness (or emptiness in the mahayana period) in his ordinary consciousness, he developed supreme detachment and he was free from suffering.
