The origin of the swasticer

Answer 1

The ubiquity of the swastika symbol is easily explained by its being a very simple shape that will arise independently in any basket-weaving society. The swastika is a repeating design, created by the edges of the reeds in a square basket-weave. Other theories attempt to establish a connection via cultural diffusion or an explanation along the lines of Carl Jung's collective unconscious. The genesis of the swastika symbol is often treated in conjunction with cross symbols in general, such as the "sun wheel" of Bronze Age religion. Another explanation is suggested by Carl Sagan in his book Comet. Sagan reproduces an ancient Chinese manuscript (the Book of Silk) that shows comet tail varieties: most are variations on simple comet tails, but the last shows the comet nucleus with four bent arms extending from it, recalling a swastika. Sagan suggests that in antiquity a comet could have approached so close to Earth that the jets of gas streaming from it, bent by the comet's rotation, became visible, leading to the adoption of the swastika as a symbol across the world. In Life's other secret, Ian Stewart suggests the ubiquitous swastika pattern arises when parallel waves of neural activity sweep across the visual cortex during states of altered consciousness, producing a swirling swastika-like image, due to the way quadrants in the field of vision are mapped to opposite areas in the brain. Alexander Cunningham for the Indian swastika symbol rejected any connection with sun-worship and suggested that the shape arose from a combination of Brahmi characters abbreviating the word su-astí.
