This is from ancient Chinese Zhuyou Shu.    

You can sit or stand. The palms are held opposite, three or five centimeters up and down. With two eyes closed, think of looking inside the palm and carefully observe the sense between the palms. The two palms can easily and slowly rotate like a grinding disc symmetrically. After a few minutes, there will be a feeling of Qi (air) between the palms. The key to achieving a quick effect is to relax the whole body and focus on the sense of Qi between the palms. You can further experience whether there is repulsion or attraction. Practice this action repeatedly with slow breathing for 2 minutes. 

When you practice to a certain extent, it seems that the two veins of your whole body (任督二脉) are also opening and closing until every pore (cell) is opening and closing, breathing, exchanging, metabolism, in the purification of nature and the cosmic field into the human body and excrete the waste in the body. This training not only adjusts your own biological field but also mobilizes the cosmic field, including high-energy information from ancestors, into your body. Doing so lets you concentrate the energy on your fingertips, allowing you to write with precision and deeply penetrate the ink paper or spell on the lesion with a pen. This intention can help you get rid of the disease and its symptoms.

In this 2-minutes practice, we just do breathing so our life shift from "doing" to "being"  and remain calm and clarity (adapted from example in [1]) :

Sit comfortably lets us be both relaxed and alert at the same time. Take a deep breath, lifting the rib cage. Let the air in as much as we can. Consider we lighted a torchlight inside our dark mind with fun and purpose. Hold your breath for 3 seconds. Then, letting go of the breath, let the shoulders drop while the spin stays gently in place and push all the air out of the cage. Thus, embody the flow of a river and the stability of a mountain simultaneously. 

Ending the meditation with joyful inner peace to arise. Breathe in, I am calm; breathe out, I smile. The present moment is wonderful. 

While doing this, keep the eye either close, open, or half open as long as we feel relaxed and focused. Feel each deep breath pumping in energy and relaxation. If any distraction, sounds, thoughts, or physical sensations come, acknowledge and experience it without judging or reacting. Remain mindful and then gently let them go. Breathing as if our life depends on it. 

In this meditation practice, we will check our posture [1]: 

1. Eye half closed or gazed into a space 
2. Tongue hole aghast the upper palate 
3. Lip slightly apart, teeth not clenched 
4. Chin tucked in slightly, "like an iron hook."
5. Shoulders relaxed, held up and back, "like a vluture."
6. Back straight "like an arrow." 
7. Leg cross in "lotus position."

We can think of us sitting like a majestic, dignified, and awe-inspiring mountain. Keep checking your posture during the meditation.  Feel the air flowing top down when we scan to check our posture. Stay relaxed and alert. 

We can use the following 2-minutes butterfly meditations practice [1] as the starting point to gain mindfulness.

Let's imagine that we are butterflies resting on a flower petal, swaying gently while the breeze lifts and lowers the flower. Our attention is the butterfly, and the petal is the breath. As we breathe, we feel the warm basking in the warm sunshine, smell the fragrant aroma of the flower, and enjoy the vibrant colors all around us.

​Remain calm and concentrated, relaxed and alert. If any distraction kicks in, try bringing attention back, remembering it's not a failure but a natural process of growth and development of powerful mental "muscle." Take a kind and curious attitude, as in a "loving grandmother mind," toward ourselves during the practices, who always love just as who we are, and we are perfect in her eye. 

 Now, let's have a walk and mediate (Adapted from [1]) 

Start by standing still. Bring attention to this body. Become aware of the pressure on the feet as they touch the ground. Take a moment to experience this body standing on the ground.

Now, take a step forward. Lift one foot mindfully, move it forward mindfully, plant it down in front of you mindfully, and shift your weight to this foot mindfully. Take a short pause, and do it with the other foot.

If you like, when lifting your foot, you may repeat silently to yourself, "Lifting, lifting, lifting," and when moving and planting your foot forward, you may repeat silently to yourself, "Moving, moving, moving."

After taking a number of steps, you may wish to stop and turn around. When you decide to stop, just take a few seconds to become mindful of your body in a standing position. If you like,
-you may repeat silently to yourself, "Standing, standing, standing."

As you turn around, do it mindfully, and if you like, you may repeat silently to yourself, "Turning, turning, turning."

If you wish, you may synchronize your movement with your breathing. When lifting your foot, breathe in, and when moving and planting your foot, breathe out. Doing this may help inject calmness into the experience.

We can practice this anytime we walk.
