Meditation is to let the space between thoughts expand in passive listening presence

The instance, which is using the past to preserve the thoughts in a linguistic form, is the inner thinker, who reacts to challenges by dividing, evaluating, comparing.

To finish thoughts, so that they can end and renew themselves, is therefore equivalent with ceasing to preserve them in a linguistic form, which again is equivalent with meditation: that, to let the thoughts rest in longer periods of time, to let the space between them expand in passive listening presence.

It is as simple as that.
