Replacing the hindrances with it's opposite?

> Similarly, wise consideration of the mental liberation of loving kindness (mettā- cetovimutti) counteracts ill will; wise consideration of the elements of effort (ārambhadhātu), exertion (nikkamadhātu), and striving (parakkamadhātu) counteracts sloth and torpor; wise consideration of tranquility (cetaso vūpasama) counteracts restlessness and worry; and wise consideration of wholesome and unwholesome states (kusalākusaladhammā) counteracts doubt.6 So lets say i am having ill will thoughts. Do i just replace those thoughts with loving kindness instead? Or if I am experiencing sloth and torpor, do i just replace and abandon those thoughts with exertion and striving? Is that how you apply this passage in the real world, by abandoning those thoughts and having one pointed focus on their antidotes?
