In Spidersilk the novel, the main character, Mark, uses his Qi to help him with his struggles. You may have noticed that the energy changed when Mark was around. For instance, when he moved into his new place, the yard slowly began to change to suit his preferences. Qi is defined as natural energy, so this makes absolute sense! Today, many still practice Qi and it is presented in everything from TV shows to ways of life! For more on Qi, check out this link!
