I’ve got a feeling that it’s important that the last OM of the meditation is at the Lower Dantien, which it might not be if you start again at the Lower Dantien or just guess where you are whenever you loose your place. The way Master Lin says the MWAA at the heart centre and the OM at the Lower Dantien is very distinctive and easy to recognise, so whenever I loose my place I focus on the heart centre for all the MWAAs and on the Lower Dantien for all the OMs until I can hear from his voice that we really are back at those two points and then I carry on from there.

Best wishes
