Hi all,
These names such as 'Shen', 'Qi', 'Ming' etc are only here to help a teacher express to the student what is happening but in truth nothing is really happening and there is no separate Shen or non-Shen. For instance, heart is often used because around the solar plexus area and below is where we feel the presence of stillness when our practice has developed. This 'feeling' or 'awareness' can also be noticed in objects around you and when this is so what is felt in the 'heart' is also felt outside the body. The confusion of heart and mind comes from meaning Mind as in Emptiness, Tao, Buddha-Nature etc and not an intellectual thought process. So what is in the 'heart' is also in the 'head' and what is 'spirit' is also what is not 'spirit'.
So my point being: these different words are used for two reasons: to help a student feel that they are progressing and for someone who has 'Awakened' to try to explain what has happened. In truth, whether you Realise or not makes no difference, nothing about you changes other than knowing IT. So there is no need to get caught up in what is Shen or not because neither Shen or not-Shen exist lol!
All the best,
Heath
