Lying low, discussing corporal punishment? (5,4,6)

I believe the answer is:

going into hiding

I'm a little stuck... Click here to teach me more about this clue!

'lying low' is the definition.
The definition suggests an adjective which matches the answer.

'discussing corporal punishment?' is the wordplay.
I cannot really understand how this works, but
'punishment?' could be 'hiding' (I have seen 'physical punishment' mean 'hiding' so perhaps 'punishment' could also mean 'hiding') and 'hiding' is found in the answer.
The remaining letters 'goinginto' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
