There was a noticeable increase in energy because my body is usually colder, but I felt very warm and calm during the retreat. After going home and doing more exercises, the feeling just got stronger and stronger.
I used to have palpitations issues. My heartbeat was very low, about mid-forties. Amazingly, coming out of the retreat, I woke up one morning feeling warm. Subconsciously touching my palms, I realized that my pulse went up and became stronger. Before I had seen both Chinese and Western doctors, they both said my pulse was feeble. The Western doctor wanted me to take Western medicine, but I refused. I tried Chinese acupuncture and other methods and medication, but it never really made a difference. But coming out of the retreat, my pulse went up and has stayed up ever since then.
