“The word Nirodha also means “restraint”.
It is not by restraining the mind that it will move and
become involved in a particular direction of choice.
It is the other way round; that is,
so strongly and intensely the mind has moved toward
one area and has become absorbed in one area
that there is no “infiltration”.
Therefore Nirodha meaning “restraint”,
is just an effect of Nirodha meaning “complete absorption”.
