Title: Pure Light
Review: Dinshah Ghadiali was a brilliant and extremely talented scientist. He was way ahead of his time and ahead of out time. His book "Spectro-Crome Metry Encyclopedia" is a complex synopsis of property of light and its use by humans. The book "Let there be light" written by Ghadiali's son Darius Dinshah is a good extract from his father book. It clearly explains application of light for therapeutic purposes. This a very useful and kind work.
