What are the six in SN 1.70? The sutta quoted below has a riddle about the six.

What are the six? And why?

What is the message of the sutta?

SN 1.70 translated by Bhikkhu Bodhi:


  “In what has the world arisen?
  In what does it form intimacy?
  By clinging to what is the world
  Harassed in regard to what?”
  
  “In six has the world arisen;
  In six it forms intimacy;
  By clinging to six the world
  Is harassed in regard to six.”
Cha Chakka Sutta is another Sutta which has a play of the number 6. Here more elaboration is given on what each set of 6 is.

The Singhala translation is less of a riddle than the English. English retranslation is mine:


  (අධ්‍යාත්මික ආයතන) සය උපන් කල්හි ලොව උපන්නේ නම් වේ. 


When the 6 sense bases arises the world arises


  (රූපාදී බාහිර ආයතන) සයෙහි සඞගමය කෙරෙයි. 


By non-reaction to the external sense objects, the world is stilled


  (අධ්‍යාත්මික ආයතන) සයම ප්‍රත්‍යය කොට ගෙන 


By means of the 6 sense bases 


  (බාහිර ආයතන) සයෙහි ලෝ වැසි තෙම පෙළෙයි (වෙහෙසෙයි)


The 6 external sense objects trouble the worldlings

ලොක ( හෙවත් ජස්සුලොක ) සූත්‍රය

අධ්‍යාත්මික ආයතන - world - internal senses - eye, ear, ....

බාහිර ආයතන - external sense objects

So what is covered here is the 1st 2 items in the list of items in Cha Chakka Sutta:


the 6 internal senses
the 6 external senses
