Yes, good point. How much does the beginner really need to know? Origination (DO), cessation (DC), the gratification (senduality, the process of sensing an object) the drawbacks (three marks, asubha, insubstantiality), and the escape (the noble eightfold path and it's fruit). Alternatively one could include all of this in the 4NT. The Okkanta Samyutta is also a nice collection of suttas which seem to contain the theory requiredfor stream entry. http://www.accesstoinsight.org/tipitaka ... ml#okkanta
Bahussuta- Buddha seems to bring in bhavanamaya panna into it. Nice quote.
