How does Theravada practice to obtain the direct knowledge of anatta? In this comment it is stated that the Pali Suttas contain the correct method for manifesting direct knowledge of anatta. I agree, but I wonder what Theravada adherents would regard as the precise suttas that definitively explain? In particular, is SN 5.10 included:


  “Why do you believe there’s such a thing as a ‘sentient being’?  Māra,
  is this your theory?  This is just a pile of conditions,  you won’t
  find a sentient being here.
  
  When the parts are assembled  we use the word ‘chariot’.  So too, when
  the aggregates are present  ‘sentient being’ is the convention we use.
  
  But it’s only suffering that comes to be,  lasts a while, then
  disappears.  Naught but suffering comes to be,  naught but suffering
  ceases.”


I ask because the Analysis of the Chariot expounded by Chandrakirti is highly praised as one of the best methods for quickly using analysis to confirm that things lack inherent nature. It is said that conducting this analysis in meditation when combined with serenity meditation is the method to achieve the direct knowledge of anatta. Just as the chariot lacks an inherent nature of "chariot" and is merely a convention, just so the person lacks inherent nature and is merely a convention.

So is this a Sutta upon which Theravada agrees as source for the analysis necessary to manifesting direct knowledge of anatta? 

How about the conversation between the Arahant Nagasena and the King?

Are there other Suttas which take precedence? What is the precise method for generating direct knowledge as opposed to mere conceptual or inferential understanding?
There's no cutting corners nor shortcuts in Theravada. SN 5.10 speaks the truth. But to actually attain direct knowledge to this truth as opposed to mere conceptual understanding, one has to perfect the Gradual trainings of Sila-Samadhi-Panna, which Ven. Bodhi did a great job of explaining in his "Noble Eightfold Path". And to each aspect of the gradual trainings, there are many different suttas one'd need to read, study, contemplate, and put into practice (ie: for Sila: AN 8.39-43, 3.70, Sn 2.4, SN 3.5; for Samadhi: Anapanasati Sutta, Satipatthana Sutta; for Panna: MN 43, AN 8.2, AN 3.73, AN 7.6, and many more as detailed in Ven. Bodhi's "In the Buddha's Words"). There're no shortage of teachers in the world who can eloquently speak at great length about all the ins and outs of anatta/shunyata and stuff. But when facing some young voluptuous beautiful women, some title, some power, some cash, etc. then the number start dropping like flies! Why? Because they're the experts of Anatta who fail the basics of Sila-Samadhi-Panna.
