I'm now back from a lovely holiday in San Francisco where I was visiting my son, who's studying at the University of California, Berkeley. I browsed in some bookshops to see which were the US bestsellers, as undoubtedly these titles will be popular in the UK before too long.
I noticed the term 'indigo children' in several titles, a term I had not heard before. Indigo children are 'special' children, believed by some to be intuitive, telepathic or psychic. The colour indigo is associated with intuition and the third eye in New Age philosophy, yoga and meditation.
Actually, maybe the books on indigo children won't make it to the shelves of British bookstores since the term has been around for several decades, and books have still not materialised here. An American parapsychologist and psychic, Nancy Anne Tappe, coined the term in the 1970s. Tappe said she noticed that certain children had indigo auras. Another book, The Indigo Children: the New Kids Have Arrived, by Lee Carroll and Jan Tober, published in 1998 popularised the term once again.
No scientific studies have ever backed up the views of those who believe in the special gifts and destiny of so-called indigo children. Many scientists believe that children labelled indigo are often suffering from attention-deficit hyperactivity disorder and would benefit more from medication than psychobabble.
The word indigo is very much associated with India, and the name of the substance (a blue dye) reflects this. Indigo is from the Greek word indikon, and Latin word indicum, which meant 'Indian substance'. A synonym for indigo, which you will definitely know if you are a crossword buff, is anil (it's the only word that will fit if the compiler is faced with _N_L in the puzzle he or she is designing). The word anil can be traced back to Sanskrit when it meant 'dark blue'.
