Somdej Toh was born in 17 April B.E.2331 in the 7th years of Groong Rattanagosin era of King Rama 1st. Even though Somdej To may act rather unfashionably but never capriciously he had been known as a highly eccentric monk. The legend has is that King Rama the fourth favord him a great deal. it was also known that King was a true expert on astrology and astronomy to the extent that he could even predict the solar eclipse in advance. The king together with his son along with the diplematic corps proceeded to WhaKoh in Prachaub and withnessed the solar eclipse - an event which surprised everyone-concerning his ability in mathematical and astrological prediction.
Before he ascended to the throne he was voted unanimously by the nobility to leave monkhood and became the King of Siam. Being a keen astrologer, he believed that the birthchart of Prince Issaresrangsarn, his younger brother, was excellent so he appointed him anohter king called "Phra Pinklauo". It was also believed that the birthchart of Somdej To was also examined by the king as Somdej To did but the king were displeased with such plagiarism.
According to his birthchart, it was known that Somdej To was a very intelligent and highly capable monk. At the time that he was born, the "Sri" or special merit was upon his ascendant. This means he would be well-known and well respected. His Mars would help him in terms of hard work. At the same time his Mars proved that he was simply an orphan so he turned to Buddhism. His Jupiter happen to be one of the highest point which certainly testifies to the fact that his intelligence was high whereas his Venus shows that he did not crave for any wealth, Saturn as well as Rahu Proved that he did not long for any possession and would live very long. His Majesty King Rama the fourth was well known for his prediction and treatise on astrology. He found that Somdej To's birthchart was amazingly good. In fact it would be far more scientific to suggest that the moment of conception would be the time when the influence of the planets would be more significant. King Rama the fourth also put forward his own interpretation for the planets without conflicting with any traditional astrological beliefs. Those who are interested in astrology may also try to interpret their signs according to King Rama the fourth's interpretation, they will be surprised that it is accurate and can explain the psychic nature that sees through to their real inner personality.
