6. Yamaka Pæ¹i
This is accomplished in the form of pairs of questions, which gives it the title of Yamaka. The logical process of conversion (anuloma) and complete inversion (pa¥iloma) is applied to determine the complete import and limit of a term in its relationship with the others. An equivocal nature of a term (saµsaya) is avoided by showing, through such arrangement of questions, how other meanings of the term do not fit for a particular consideration.
The following pairs of questions may be taken as an example:
To the question ‘May all rþpa be called Rþpakkhanda?’ the answer is ‘Rþpa is also used in such expressions as piya rþpa (loveable nature), eva rþpa (of such nature), but there it does not mean Rþpakkhandha.’
But to the question ‘May all Rþpakkhandha be called rþpa?’ the answer is ‘yes’, because Rþpakkhandha is a very wide term and includes such terms as piya rþpa, eva rþpa etc.
