Sometimes, rather than following the breath or saying our mantra, it is enough to sit quietly with gently open eyes. This is best done in a garden or a place where there are trees and plants. If there is water around so much the better. At first there may be nothing but a babble of internal trivia. We can’t control it but simply have to wait until all the mental mud settles and the pool of the mind becomes clear. ‘Launch into the deep’, says one writer, ‘and you shall see.’ The secret of seeing is a pearl of great price.
