About This Answer
Asked whether sitting or walking meditation should come first, Ajahn Dtun replies that there is no fixed rule. If the mind wants to sit, sit; if it wants to walk, walk. What matters is training the mind to be peaceful every day until practice becomes a habit.
He then turns to why sitting often does not become calm. A meditator decides to stay with Buddho, yet lets the mind drift into thoughts of the past, the future, work and worries, and then complains that the mind will not settle. The practice is to make a firm determination not to think of anything except Buddho, and each time the mind wanders, to bring it straight back.
This takes patience and persistent effort, because the mind has followed its thoughts for countless lifetimes. He compares it to athletes, who cannot play well without training.
