I often hear of people when they have a dream or something they want to manifest they say that they "meditate on it," and I'm not sure what that means. In meditation we move away from activity so does this mean they are creating a mantra based on an affirmation of what it is they are trying to manifest, and using that as their mantra?
It can mean many different things to different people, but I admit that I haven’t heard it used as a way to meditate with a mantra based on an affirmation. Usually if people say that want to meditate on something, they want a period of silent mind and clarity for insight and a broader perspective to emerge on some issue they are pondering. This understanding can come after meditation itself, or during meditation if it is a contemplative practice.
