In 2003, doctor Heidi Yellen conducted a study on the frequencies of fabric. According to Yellen’s research, the human body has a signature frequency of 100, and organic cotton is the same – 100.
The study showed that if the number is lower than 100, it puts a strain on the body. A diseased, or nearly dead person, has a frequency of about 15, and that is where polyester and rayon register. Nonorganic cotton registers a signature frequency of about 70.
However, if the fabric has a higher frequency, it gives energy to the body. This is where linen comes in as a super-fabric. Its frequency is 5,000. Wool is also 5,000, but when mixed together with linen, the frequencies cancel each other out and fall to zero. In the study, even wearing a wool sweater on top of a linen outfit collapsed the electrical field.
This could be explained by the idea that the energy field of wool flows from left to right, while that of linen flows in the opposite direction, from right to left.
This could be the reason behind the concept of sha’atnez: Jewish law forbids sha’atnez – wearing garments of mixed wool and linen. The wool and linen may not be spun, woven, sewn, tied, knotted, or knitted together for garment use. Even one linen thread found in a large garment of wool renders the entire garment sha’atnez.
