When meditators are learning to stabilise the mind, they should not regard meditative equipoise as something good. If they fail to have an experience of meditative equipoise, they should not regard that is a failure. The important point is not whether meditative equipoise is present, but whether you can maintain awareness in both a settled and a disturbed state of mind. If disturbing thoughts arise, you should use them with awareness to recognise that thoughts are transient — they arise, persist for a while, and then disperse. The transience of a thought is revealed by its elusiveness. Before you can get hold of a thought, it is already gone, and another one has appeared in its place.
