Hakini-god of the Forehead 6th Chakra
Place all the fingertips together. The Hakini Mudra can be practiced at any time.
When you would like to remember something, or want to find the red thread again, place your fingertips together, direct your eyes upward, place the tip of your tongue on your gums while inhaling, and let the tongue fall again while exhaling. Then take a deep breath-and what you wanted should immediately occur to you. Moreover, when you must concentrate on something for a longer period of time, could use some good ideas, or want to remember something that you have read, this mudra can be useful. When doing mental work, don't cross your feet. Sit with your eyes facing west. This mudra can do true wonders, and you should always keep it in the back of your mind in case of an emergency.
In terms of science, this finger position has been researched quite well; researchers have determined that it promotes the cooperation between the right and left brain hemispheres. It is also recommended today in memory training and management courses. It is said to open access to the right hemisphere, which is where the memory is stored. This mudra also improves and deepens respiration, and the brain profits from it as well.
Lungwort (Pulmonaria officinalis L.) benefits the lungs.
You may also improve concentration and gather new mental powers by letting your gaze and thoughts rest on one object or a relaxing activity for a longer period of time. The following exercise also helps in this direction.
About three feet in front of you, imagine an object, such as a burning candle, a piece of fruit, or a stone. Look at the object as long as possible without blinking. Now close your eyes and try to imagine the object. Immediately let go of every rising thought not related directly to the object. Hold your concentration as long as you can.
Concentration is my strength.
