Hi ,
In my notes, I have the lymph system connected to the liver system(detoxifying). Also, that the liver and heart systems are closely related, but perhaps more as a detail regarding another category of illness's.
Master Lin mentioned the lymph nodes as a last resort holding area of toxins, not being processed by the liver. Them being effected, is a serious warning sign in a connected spreading of this blockage, and taking them out, not being a good thing, as they are a last resort place to hold toxins.
If anyone has something to add or clearify, regarding this, please be my guest. SFQ, only, please, as not to confuse the methods.
There might be additional focus on the belly/abdomen area and related organs to the digestive system.
Apples are good for the liver. Cut out the red meat. Holding the ring finger to the thumb, as a hand position, helps this system. One hand or both, anytime. Put the right message in the liver. Green energy.

There is so much to be gained through practice of level II material. You could be clearing every primary organ channel in a most effective way. or, If you can detect energy blockages, you can preferrably go by that information, regarding where to focus. Or, as I say, just go through a complete clearing of spine, organs , etc.. , while your scanning abilities kick in.
If people make requests, it is certainly okay to listen to them, but, proceed, by detecting blockages and clearing them, wherever they might be. If you aren't sure, just go through a complete clearing of primary organs and spine, etc..
love,
