MN 10 wrote:"There is the case where a monk remains focused on mental qualities in & of themselves with reference to the five hindrances. And how does a monk remain focused on mental qualities in & of themselves with reference to the five hindrances? There is the case where, there being sensual desire present within, a monk discerns that 'There is sensual desire present within me.' Or, there being no sensual desire present within, he discerns that 'There is no sensual desire present within me.' He discerns how there is the arising of unarisen sensual desire. And he discerns how there is the abandoning of sensual desire once it has arisen. And he discerns how there is no future arising of sensual desire that has been abandoned. (The same formula is repeated for the remaining hindrances: ill will, sloth & drowsiness, restlessness & anxiety, and uncertainty.)
So perhaps this isn't a "doing" in the sense you mean, but it's also talking about an aspect of the gradual training which is elsewhere written about thusly:
MN 107 wrote:“He resorts to a secluded resting place: the forest...a heap of straw. On returning from his almsround, after his meal he sits down, folding his legs crosswise, setting his body erect, and establishing mindfulness before him. Abandoning covetousness for the world, he abides with a mind free from covetousness; he purifies his mind from covetousness. Abandoning ill will and hatred, he abides with a mind free from ill will, compassionate for the welfare of all living beings; he purifies his mind from ill will and hatred. Abandoning sloth and torpor, he abides free from sloth and torpor, percipient of light, mindful and fully aware; he purifies his mind from sloth and torpor. Abandoning restlessness and remorse, he abides unagitated with a mind inwardly peaceful; he purifies his mind from restlessness and remorse. Abandoning doubt, he abides having gone beyond doubt, unperplexed about wholesome states; he purifies his mind from doubt.
So satipatthana very much underlies doing this with the hindrances, which concomitantly develops the awakening factors.
