Practices    (Patipatti) How to Tell if One's Practice is Right or Wrong               It is important that the practitioner realizes when his practice is right or wrong. With the right practice he will know the posture and know that the posture is sitting rupa. Also, the yogi will realize that the posture is sati, and that sitting rupa is sampajanna. And he will know these two together. If he is aware of sitting rupa with practice wisdom, he will know by the feeling that this is right. This right practice wisdom repeated over and over will lead to vipassana wisdom.             He should know that the duty of Satipatthana is to destroy like and dislike. For example, if he doesn't like wandering mind, then dislike (domanassa) will develop. On the other hand, if he would like to be in the present moment because it is peaceful, then desire (lobha) will develop. So correct practice is to be in the present moment as much as possible - which will destroy like and dislike.             When the mind encounters an object, states with either no defilement (present moment) or with defilement (mental, or nivarana, kilesa) will arise, depending on whether one's yoniso is good or not. Suppose the mind encounters "foong" (mental kilesa), if yoniso is not good, aversion (domanassa) can occur. But if yoniso is correct, it will be clear that foong is nama (a mental state), and it is not "you" - and you will be back in the present moment.
