Hi Retro, Ana, and, Dukkhanirodha,
Im am interested in this idea of "Super mundane motivation". It seems to me that making the mind serene, gratified, and joyful are key aspects our practice. My understanding is that these aspects are important conditions but not ultimate ends in themselves. In this Sutta the Buddha is speaking to a group of lay followers and I expect that his words were meant to be understood on a practical level. I mean that the Buddha intended his words to create an impression of meaningful distinction for those who have not seen his truth for themselves. Do you think that characterizing a type of generosity with the attitude 'This is an ornament for the mind, a support for the mind' is meant to convey something like generosity with an attitude which does not look for an end but is aware and appreciative of progressively supportive spiritual beauty?
