Are feelings (vedana) always caused by ignorance? The Pali suttas often refer to feelings or 'vedana', as follows:


  There are these three kinds of feeling: a pleasant feeling, a painful feeling and neither-pleasant-nor-painful feeling. MN 74
  
  There are these six classes of feeling: feeling born of eye-contact, feeling born of ear-contact, feeling born of nose-contact, feeling
  born of tongue-contact, feeling born of body-contact, feeling born of
  mind-contact. MN 9
