You can read a much more in-depth Jewish approach to this subject HERE.
But in the meantime, this is one of my 'go to' techniques for starting to get the energy flowing properly in the nefesh level of soul again:
The technique is very simple: Before you go to bed, use some micropore-type medical tape to stick a WHOLE lentil on the places on your hand marked above.
When you wake up in the morning, see which ones have cracked - those are the areas that really need some work. If all your seeds crack overnight - that shows you're pretty exhausted on the energy front, and you may need to take a long, hard look at what needs to change for you to start enjoying your life more.
Keep sticking the seeds on every night (using new lentils...) until they stop cracking.
If you're very exhausted, or if one area is particularly weak, it could easily take a week or two, but don't give up!
Strange to say, lentils have brought me through some extremely stressful, taxing periods of life when my physical energy was literally crashing through the floor.
As always, if you want more background on energy meridians, and how it fits together with physical health and the spiritual side of things, pick up a copy of Talk to God and Fix Your Health, HERE.
