About This Answer
How should one meditate when unwell, such as when dizzy or nauseous? Ajahn Dtun acknowledges that meditating while ill is very difficult, which is why the skill of calming the mind should be developed while health is good. Someone who has learned to make the mind peaceful will know how to do so when sick, even if the body still feels unwell.
Normally the mind attaches to painful feeling, and that attachment intensifies the pain. One can use mindfulness and wisdom to reflect that the pain is just a condition arising in the body, not the mind. A practitioner who has strongly cultivated sīla, samādhi and paññā can separate the mind from painful feeling, see that it arises due to the body, step back, and so not suffer. He admits this is hard: letting go of attachment to body and pain, even temporarily, takes skill, but with that skill the mind can enter a peaceful state.
