In each instance that is arising the right method follows (6,3)

'in each instance' is the definition.
I know nothing about this answer so I can't tell whether it can be defined by this definition.

'that is arising the right method follows' is the wordplay.
'that is' becomes 'ie' (short for Latin 'id est', 'that is').
'arising' shows that the letters should be reversed in order.
'right' becomes 'r' (common abbreviation).
'method' becomes 'way' (way of doing something).
'follows' means one lot of letters go next to another.
'ie' written backwards gives 'ei'.
'ei'+'the'+'r'+'way'='EITHER WAY'

Can you help me to learn more?
