Sun style Santi connections:
Builds upon the wu chi and Tai Chi postures
In addition to the 6 directions, there are many lines, triangles, etc. within the internal mechanics of Sun style Santishi. Yi Jin Jing is also a deeper component to Sun style. This requires the guidance of a teacher to do. Santi can also be done in a "yin/nutritive intention" or a "yang/force discharge intention". This also requires the guidance of a teacher to do.
Here are a few internal connections to get started. I hope to post more as time allows. As usual please feel free to contact me for more information.
Look up the point locations somewhere on the web if you are not familiar with the names.
Triangles:
1.) lead hand shenmen, tip of elbow, and heart one
2.) hip, knee cap,heel
Straight lines:
1.)baihui, huiyin, that line projected to earth
2.)shenmen, mingmen, heel
Don't forget to keep the spine/Du Mai extended and the Ren Mai relaxed. This last part is probably the most important.
