Let me relates one story,
A Muslim woman once came in the monastery in Indonesia, to learn meditation.
In that monastery they are practicing Mahasi method.
First attempt the woman leave after three days
Second attempt, with strong determination, she could see her own thoughts, how it behave
how is the form, how it ceases etc.
Now please tell me I asked you again twice, have you seen this?
Do you think that muslim woman had learn aggregates, bases etc..?
In one of the sutta " a person who studied Dhamma, without realizing it is like a shepherd who counts other's sheep, not the owner of the sheep"
This sutta is brought by The Buddha because of one dispute between practitioner of Dhamma and theoreticians of Dhamma, The Buddha asked something related to theory to Theoreticians, they can answer well, but after The Buddha asked something relating to practicing experience, the Theoreticians unable to answer.
Only practitioner can answer.
