Whatever sensory experiences we go through, if we go through them with mindfulness and awareness, there is no limit to how far we can go. The limit is mindfulness and awareness. Even if we don’t enjoy the experience, that itself becomes a trip. The nonenjoyment becomes a cause of suffering. That’s why, if we don’t practice mindfulness and awareness, asceticism just becomes pain rather than a cause for liberation. That’s why Buddha said to forget about asceticism. That’s what Buddha did. He left asceticism, became very mindful in every step, and achieved enlightenment.
