When it comes to spiritual practice, the first thing that comes to mind is probably religion. Indeed, in the process of practice, we cannot do without some religious practice methods, because none of the subjects we know of currently can truly and comprehensively explore the "self", and from ancient times to the present, only religion has been exploring this issue. While these enlightened people and saints have pointed out the direction for us, they have also summarized some very practical practice methods for us. However, practice does not mean that we must enter a certain religion. More and more awakened people are willing to pursue their own hearts and use some religious practice methods to find that "self". This is spiritual practice.
Find me, find my true self!
