Thunderbolt Pose (Vajrasana)
Shin-shin-toistu-do is a variation of yoga brought to Japan in the 1940s by Tempu Nakamura. This form of yoga focuses on developing Ki (life force) through seated and moving meditation, breath techniques and stretching. Vajrasana or seiza as it is known in Japanese is an important posture of this tradition as it helps to keep the body relaxed aiding in meditation. It was also the traditional way of sitting in Japan although now mostly practiced at tea ceremonies and martial arts.
Though it is simple in appearance, vajrasana offers many health benefits such as increasing blood circulation and strengthening sexual organs. It also helps with digestion, constipation and stomach dysfunction. Overall this pose is wonderful with the lower body, since it tonifies hips, thighs and calf muscles.
