Experiences that arise from practice are called nyams. The general advice with regard to these experiences is to let them go – they are simply an indication that you are practising. To regard nyams as special can tend to make you want to seek them out. If, for example, you experience a particularly strong nyam during a meditation session—such as a feeling of bliss, or a powerful visionary experience—there is the danger that you then start to look for this experience again whenever you practise. You can then turn your meditation sessions into trying to return to that experience – forgetting that the nyam arose spontaneously simply through your practice.
