This is an exercise to help you develop and improve your intuition. It is called a third person meditation and it is designed to help you observe, assess, feel, and be validate what you are sensing. 

You first begin with a meditation.
Use a meditation technique and process you are comfortable with. 
Now, visualize yourself leaving your body and now sitting opposite of yourself.
Tune in and observe what you see, sense, and feel as you begin to ask this other 'self' some questions. 

Ask questions, such as "what are you feeling?"
Now, observe what hints you start to see, feel, and sense as this other 'self' responds to your question. Notice the emotions and feelings being portrayed or projected from this individual. In other words, analyze this other 'self' as a person in front of you, but be objective in this process. Also,make sure you only do this using a positive aspect. You don't want any negativity being part of this inspection process.

You can also add other topics and question - things that you would like to know about yourself, for example.Some thoughts or responses may be expressed through your unconscious self, Higher Self, or even spiritual self.

If you did this exercise in front of a mirror, the process would then become a mental exercise rather than an exercise to develop your senses. The objective of this exercise is to understand your feelings and develop your intuition. This is why you do this exercise in a meditation rather than a mirror.

This type of questioning & observation process can help broaden your ability to sense your different feelings. It can also help you tap into gaining a greater understanding of who you are and how you really feel. It can also help improve your intuition abilities using all your senses. This is why this exercise works - you are tuning into your feelings and senses and then using an internal process to validate what you sense.

This exercise will help strengthen your ability to tune in,sense, and develop your intuition.  

Qigong exercise for the kidney, led by Barbara Branaman.

This is another example of the Brocades Qigong exercise. This exercise is demonstrated by Master Jesse Tsao.

Part of the Qigong experience is learning to direct the subtle energy Qi and move it where you want it to go, and to do what you want it to do. We do this through tuning in, sensing, and visualizing where you want the Qi to flow and then visualizing what you want the Qi to do.  The final step is to to gain an awareness and understanding that indeed things happened and changed as you directed.  
So having Qigong students experience the changes that occur when a person directs and sends Qi, or experience a change when a vessel is infused with Qi, is often an important step in the learning process. When I saw this demonstration by Robert Peng on how he could infuse Qi into a glass of brandy and how it actually changed the taste of the drink, I thought this would be an excellent test to give to my Qi Cultivation students. This type of experiment could help them verify what happens when Qi is infused into a vessel.The only problem was I couldn't provide alcohol in our class, so I decided to test this using WATER.

I took a sealed bottle of spring water to class. I poured half of it into a water pitcher and kept the rest in the plastic water container. I then held the water picture with my left hand and used my right hand, with palm facing the top of the water pitcher, to direct Qi into the water. I visualized drawing Qi up from the earth, up through my body, and then out the palm, and into the water pitcher. I changed to sword fingers, then changed to crunched fingers, then back to flat palm, all with the intent of infusing vibrant Qi into the water.  
After a couple of minutes, I stopped and we did a taste test with the two different waters; a glass of water from the plastic water jug (that had not been touched), and a glass of water that had been mentally infused with earthly Qi.
ALL of us could taste a difference in the water. ALL OF US!  
The water that had been infused with Qi was fresher!  It tasted like it had just come from a clear mountain spring. It felt lighter, and more slippery.
The water from the plastic jug tasted stale and 'minerally'and hard.
This class experiment gave us a physical validation of what can happen when we direct Qi into a vessel; things change and improve. 
This was an effective exercise to help us physically experience what directing Qi into a vessel can do. We essentially do the same thing with Qigong - we direct vibrant Qi into our bodies or into a patient) and things improve. It at times feels like magic, but all it really is, is improving the quality of the Qi.   

The Eight Brocades, also called Ba Duan Jin Qigong, is one of the officially recognized qigong health forms. The Eight brocades has also become a template for many modified styles, such as Shaolin style, Yang style, & Wudang style. This video is one of the more easy-to-follow demonstrations of the Eight Brocades Qigong exercise.

Here are some good videos that demonstrate Qigong exercises to benefit the heart.

This demonstration of the Qigong exercise to help heart transplants is really an exercise for ANYONE who wants to nourish the energy for the heart. It is easy to follow and she is clear in her instructions.

This next video is a Qigong exercise called "the Red Crane" and incorporates using the sound of 'HAW' as a way to release anxiety and frustration. The video is from Heath and Nicole Reed.

This next video is a bit more complicated, but it is a good demonstration of how to use Qigong to help the emotional healing in the heart. 

Robert Johnson, MD, Kaiser Permanente chief of Palliative Care in Walnut Creek, Calif., has practiced tai chi and qigong since the 1970s. He believes these mind-body exercises promote good health, flexibility, strength and balance, which help reduce the risk of falling among seniors.

In this video, Dr. Johnson demonstrates  exercises of the seven main joints; the neck, shoulder, elbow, wrist, waist, knees, ankles. He also shares why putting the tongue on the top of your palette is important. In addition, he shares how you need to pay attention to three different circles when you are doing Qigong exercises.  He shares how the legs and feet connect and move through the earth and how all these movements are symetrical and connect back to the earth and that energy. 

Traditional Chinese exercises, such as Qigong & Tai Chi, have been found to promote health, strength, flexibility, & balance. Thanks to Kaiser Permanente for sharing this video.
