What is the difference between neutralising raga and dvesha and removing raga and dvesha? is it necessary or possible to remove raga and dvesha?

dear friend,in neutralisation both raga n dvesha remains active while removal of both is't possible.according to gitait is possible for a person to keep him neutral towards both.it is must for aperson running on spritual path because these two are obstical ofthe said path i.e.gita...34/03.in gita both are implied w.r.t. respective fields of sense-organs.
