"Shippou"　Madder Red【Hand-dyed Tenugui】

"Shippou"
The Buddhist term "Shippou" refers to the 7 precious materials (gold/silver/lapis lazuli/quartz/coral/agate/giant clam).
They are used to solemnly represent the beauty of Amitabha's Pure Land.

The seven treasures as written in Buddhist scriptures
refer to gold, silver, lapis lazuli (a blue stone), coral, agate (emerald), quartz (crystal), and giant clam (a beautiful shell), it is thought.
This circle has a meaning of eternal bonds and amplification, and it is intertwined with a design representing harmony and auspicious omens.

To begin with, in Buddhism 7 and 3 are "auspicous numbers" (numbers that call upon good fortune). These treasures are believed to bring spiritual power to oneself and protect one from calamities. eThe numbers 3 and 7 are deeply related to the Buddhist memorial traditions held 7 days after death, 49 days after death, and 2 years after death (the 3rd time the day passes).

The origin of shippou is said to be in Egypt; in the Chinese Han era, and the Japanese Nara era, the deceased also were buried with shippou among their possessions.
As it happens, there is a traditional Japanese craft making technique called shippou-ware, but this word is derived from the practice of "making pottery that is as beautiful as shippou."
