This is how the power of the science of Graphology was described in a Sanskrut (Popularly and wrongly spelt as Sanskrit) verse.
The translation is self explanatory. While describing the power of the Science of Graphology, the verse says that it (the Science of graphology) allays all doubts about the person or his text message. The science also reveals the meaning hidden in the text - Something like factual lies or other facts, which are not mentioned in the text. While further describing the strength of the science, verse says that the science is as good as World’s eye. It can reveal everything to the world. And the one who is not willing to use it, is as good as a blind.
Graphology / Handwriting Analysis was a well developed science, originated in ancient India and then spread over the world, especially in Western countries through China and then Middle East, over the period of time. Continuous invasions of Islamic Rulers and the European countries closed the old schools of education systems in India and most of the sciences had slow deaths or remained in few books or with few people.
In last two centuries, more research work was conducted in Western Countries and new generation is trying to learn it with the help of it.
The last reference of the Science of Graphology is found in the literature of Shri Ramdas Swami, the great Saint from Maharashtra and the Guru of great Hindu Warrior Shri Shivaji Maharaj, who saved the entire South India from the Islamic invasion. Shri Ramdas Swami was instrumental in focusing his goals and giving him vision to build the empire. Shri Ramdas Swami, though a Brahmchari (self declared bachelorhood in service of the God) himself, almost touched each and every subject related to day to day life, including 'How to get the best of the bricks' to 'Importance of a exercise in a life of an individual'.
He wrote in details about how the mindsets can be read from the handwriting and how the bad handwriting affects the mindset. He also prepared the charts of ideal scripts, which can be considered as charts of Graphotherapy in today’s context. Some of the references are found in 'Dasabodha' written by him. Probably, that is the last reference of Graphology in Indian scriptures.
Credit for the modern Graphology goes to the European Graphologists, especially graphologists from Germany and France. With their pain staking research, they have taken this science to a much higher level.
