@Embodied: Satipatthana (and Anapana) can be done by anyone at any stage. One just needs to be mindful and stay away from dasa akusala, and also cultivate kusala/punna kamma.
Vipassana can be done by anyone too, but it will become more effective as one starts comprehending Tilakkhana. In a way, this is also true of Satipatthana (and Anapana), since one will become better at it with an understanding of the “true nature” of this world.
