The difference lies in the outcome of the teaching. A vāsanābhāgiya sutta, like that given to Upaka, doesn't result in the arising of the Dhamma eye (i.e. the attainment of stream-entry or higher) in the listener, nor is it intended to. Any sutta where the Buddha limits his teaching to dāna, sīla, heavenly rebirth etc. is classed as vāsanābhāgiya.Manapa wrote:I was going to add is it something to do with the difference in style such as one being a teaching the other a conversation, or something of the like that poped in my mind at the time!
