  Yuganaddha or Yuganandha Sutta
Ananda tells the monks at Ghositārāma, 
in Kosambī, that those who have attained arahantship have done so in one of four 
ways: Kosambī
  - by developing insight preceded by calm, 
- or calm preceded by insight, 
- or calm and insight together, 
- or by having a mind utterly devoid of perplexities about the Dhamma. 
  A.ii.157.
