Thank you Lal for your reply.
So to go with that very last point:
- The bottom line: One must understand the ‘previously unheard deeper teachings of the Buddha’ to attain any magga phala, including the Sotapanna stage. That means understanding how kama sanna triggers avija in the mind!
I think what would be helpful for me is to have a formalized, systematic way of doing this.
If I was to take what you say and make it into something like that, I would think, “note the input, recognize the sanna, realize it causes avijja, note its unreliability.”
Perhaps whatever post you will write to thoroughly describe the first stage of Ānāpānasati will be better to my satisfaction and will fit my individual needs better. Again, thank you for your helpful comments.
