könnte auch makyo sein..ich habe dazu in meinem Blog geschrieben:
While sitting in meditation, all kind of conditions may arise. Thoughts, the ceasing of thoughts, dreaming, sensations… whatever. But also some kind of strange things may arise like hallucinations. So some people hear strange sounds, perceive odd body awareness like they shrink or grow, they feel like they start vibrating, floating, spinning and so on. Even optical illusions like colors or demonic grimaces may appear.
Of course with this experiences, no matter if they are perceived as satisfying or terrifying, great uncertainty may arise. In zen these experiences are called makyo. the translation is like “devils cave”. Yasuntani roshi pointed out that the term ma refers to mara, the temptation, and kyo can be translated as condition,realm or place.
We dont give any meaning to it but try neither to be distracted nor getting lost in it. We just return to sitting and sit through all conditions. We just recognize this apperances as clouds in the sky passing by, anicca and anatman.
Of course, if we have the feeling that these experiences affect our life especially in post meditation we should concider to consult a doctor.
