Left hand: Place your thumb joint on the nail of the index finger. Do four times a day for 4 minutes or, against acute complaints, until it has an effect.
This mudra is primarily effective when someone with a weak back has engaged in an activity (for example: garden work or cleaning) that has strained the back too much
and caused painful tensions, or when someone has sat too long in the wrong position. Backaches can have a great variety of causes. Most people have waste deposits and signs of wear, but these don't necessarily have to be painful. A diseased organ
whose nerves run through the spinal column can also cause pain.
Continuous mental strain, fears, meals that are too heavy, too little sleep,
and/or too little exercise are other causes of pain.
This mudra can be even more effective in a position that relieves the
back . When doing so, keep the chin pulled in
a bit so that the neck is stretched. This little bit of tension has an effect
down to the small of the back. After just 20 minutes in this position, the intervertebral disks are optimally nourished once again and the metabolism operates in full swing again. Perhaps you can even do this exercise during your lunch break at the office. Then you can get through the entire day without pain. What you think while you do this is also very important, which is why the image and the affirmation are particularly significant in this position.
