Mr. Thirachai Phuvanatnaranubala studied economics at the London School of Economics and qualified as a Chartered Accountant in England. He was Deputy Governor of the central bank in Thailand before becoming the Secretary General of the Thai Securities and Exchange Commission and later Thai Minister of Finance. He took up astrology as a side interest, became totally immersed in the subject and came up with the idea of spreading this useful knowledge to the world. Mr. Kornaek Khongpurttiroj (born 1972) studied Business management in Thailand for his first degree. His interest in astrology began during his undergraduate years. He explored many types of Thai astrology, and narrowed down to the method used in this book. Through his study and practice of Thai astrology for over 15 years, he was able to refine the selected method that can be readily applied by most readers.
