bahuvedanīya sutta
Bahuvedanīya Sutta:Pañcakanga asks Udāyi (Pandita Udāyī,says MA.ii.629) how many kinds of feelings theBuddha mentions.Udāyi answers that there are three:
pleasant, unpleasant and indifferent.Pañcakanga,however,insists that there are but two:pleasant and unpleasant.Ananda,overhearing the conversation,reports it to the Buddha,who says that both Pañcakanga and Udāyi are correct because he himself classified feelings in various ways; sensual pleasures might be pleasant,but are not the highest pleasures; far better and more excellent are the pleasures enjoyed by a monk who develops the four jhānas,the plane of infinity of consciousness and the plane of nought.
M.i.396ff.; the Sutta is repeated at S.iv.223ff.,under the name ofPañcakanga Sutta.
