The images above are of an example of Hiseki Davey's award-winning kanji calligraphy. Davey Sensei is a direct student of the late Kobara Ranseki Sensei, the founder of Ranseki Sho Juku Japanese calligraphy. Kobara Sensei was, with over 50 years of training, widely regarded as one of the preeminent masters of shodo brush calligraphy in the world.
Kanji are the Chinese characters used in Japan, and they often amount to abstract drawings or pictograms. In the artwork above, Davey Sensei combined calligraphy using gyosho and sosho scripts. Gyosho is a semi-cursive form of writing, and sosho is a fully cursive and abstract version of Chinese characters. (Left click with your mouse to zoom in on each image.)
Generally speaking, the brush writing states that we should believe in, and have confidence in, the Spirit of the Universe. It relates to Shin-shin-toitsu-do, the art of Japanese yoga and meditation. Davey Sensei is also the author of Japanese Yoga: The Way of Dynamic Meditation.
Davey Sensei, is known throughout the world as the acclaimed author H. E. Davey, the creator of Brush Meditation, Living the Japanese Arts & Ways, The Japanese Way of the Artist
