Action: Identify a person to be followed. Follow them; but do not in any way menace them. rather, give up your initiative to them. Never make yourself known or allow yourself to be noticed by them. If you sense that they have become aware of you, cease the stalking immediately.
If your first target disappears, then find a second and follow them.
Spend at least half a day on this, preferably longer. Commit yourself to take buses, trains, etc. whatever is necessary in order to follow your ‘target.’
Real, oppressive stalking is fueled by an intense obsession; here there is no obsession, there is only submission to the other. This should dissipate any intensity. This liberation is what you should aim to express.
