Practices    (Patipatti) Samadhi               It is not a good idea in this practice to have too much samadhi. Sometimes with the sitting position, the yogi will only know sitting posture, but not sitting rupa, or in extreme cases the yogi will not even be aware of the posture. This is caused by excess samadhi. To reduce this samadhi, some type of vigorous exercise is helpful: doing tasks, walking fast, or even running. In any case, if there is too much samadhi in any position, the position should be changed.             On the subject of samadhi, Aachan Naeb said: 'Samadhi that has Satipatthana as the object will not result in abhijjha, because it leads to wisdom - wisdom that realizes suffering. (This is one way to know if one's practice is correct).             "Samadhi that makes one happy is not satipatthana, because that samadhi is not purity. That samadhi has kilesa. Though it creates happiness, it cannot destroy vipallasa (perversity of perception). That kind of samadhi is sankhara khandha (mental formations, volitional activities) and thus part of the Five Khandas (rupa and nama) and can't extinguish suffering-i.e., reach nibbana. (Nibbana is also nama, but it is nicca, and sukha because it is not one of the Five Khandas)." The brief thought-moment that is nibbana has no feeling.             Sometimes the yogi will have so much samadhi that he will lose the feeling that is sitting rupa. But he still thinks he feels sitting rupa, because he lacks sikkhati to tell him that sitting rupa is no longer being felt. Also, if sikkhati is lost, the yogi might feel dukkha but not realize it is sitting rupa that has dukkha. He will think it is "he" that feels dukkha, so he will be practicing with the idea that "he" sits, suffers, etc., and won't be able to get rid of the wrong view of self.             The yogi must remember that the position is not just "rupa", but sitting rupa, standing rupa, etc. Otherwise he will think that the same rupa, stands, sits, etc. If he thinks this, he will not be able to destroy the idea of "compactness" and he will think that the body is himself.             First the yogi knows sitting rupa with yoniso; he then observes sitting rupa with yogavacara. When pain occurs, yogavacara knows it is sitting rupa that suffers. When change of position is made, yoniso knows the change is to cure suffering, and this yoniso prevents abhijjha and domanassa from entering during the position change.
