I'm trying to find a specific sutta I think
Upaddha Sutta: Half (of the Holy Life)


  Don't say that, Ananda. Don't say that. Admirable friendship, admirable companionship, admirable camaraderie is actually the whole

  companions, &amp; comrades, he can be expected to develop &amp; pursue the
  noble eightfold path.
