Ian Lawton has put a tremendous amount of work into his books, adding new thoughts and material as he goes, and, with the ability today to scan the material available and to involve others in gathering material in what should be the most important question that any Human asks themselves; who are we, and where do we go from here, and is certainly a leading source of Spiritual awareness!
Anyone with an open mind seeking answers, need go no farther, as, Ian has consolidated past and present studies others have made and some remarkable stories are told, that, with the resources available today can be followed up thro' the Internet and elsewhere!
He also, with enthusiasm, puts forward some possibilities which spur discussion; many linked to Science, which, if used with ongoing theories, can result in parallel awareness with spiritual philosophy of hundreds, if not, thousands of years! Too many scientists have a locked door on philosophical thought, which is their loss - it need not be ours!
