What are the catalysts in eightfold path which speed up our endeavor? I want to know how one can speed up his spiritual practices (8 fold path). For- Example, How one can improve his samādhi or prajñā quickly? And what are the things or acts which helps one to improve these quickly.
In my opinion, the best catalyst is meeting highly realized people in real life to see how they behave. In a day of that you get more teaching than in a year of reading books.
