I completely agree. Much of the work comes from the paramis of our past lives. Okay, I’m starting to understand. I don’t have much knowledge in the Abhidamma but, I made a connection with your statement. Knowing that the cittas follow one another by the billions in a second, the lokuttaras cittas of each stage of the magga phala followed each other at incredible speed, in the case of Venerable Sariputta.
So that means that in the example of arahant Bahiya he went through the 4 stages in a few seconds. It happened so quickly that it seems like he just became an arahant without the other steps of the magga phala.Lord Buddha said that “the mind is the fastest thing in existence.”
I don’t know if that’s what you meant sir. This connection with the Abhidamma just allowed me to understand this point.
