Counteract laziness with inspiration, endeavor, faith, and refinement achieved through training.
Counteracts forgetfulness with sustained presence.
Dullness and wildness are counteracted by using awareness that knows the condition of your state of mind.
Counteract lack of effort by urging yourself to apply the right antidote when defects occur in the meditation.
