Biography

According to Abu Muhammad al-Hassan ibn al-Waziri, who was a student of the polymath, Abu Zayd al-Balkhi was a man whose face was covered in scars that he acquired following a bout with

, the ruler of Balkh and its surroundings, appointed him as secretary or writer. In reality, he was offered both a writing and a ministerial position by the emperor. Al-Balkh, on the other hand, declined the latter and accepted the former. The king respected his decision and rewarded him handsomely. Sometime after this, he traveled to Baghdad again, before returning to Balkh for the last time and staying there up until his death.

Phobias

in the 9th century, calling it Fazaa'. As of today, it is still defined in a similar manner as to what was described by al-Balkhi. Al-Balkhi details the disorder as an extreme type of fear that results in the anxiety levels of a person spiking due to increasing the depth of blood in the body. This causes the person to become shaky and disoriented, preventing them from making decisions in a timely manner. Rather than taking medicine or proceeding with

, which were common methods to help an individual, he suggested gradual exposure to the object or situation that caused the fear. This technique was known as reyadat al-nafs.


Sexual attributes

While the topic of sex is more widely discussed today, al-Balkhi explored the subject in detail, specifically various sexual attributes and the affects that they have on an individual. A specific talking point that he mentioned in his work was the act of remaining
abstinent Abstinence is a self-enforced restraint from indulging in bodily activities that are widely experienced as giving pleasure. Most frequently, the term refers to sexual abstinence, but it can also mean abstinence from alcohol, drugs, food, etc. B ...
. By doing so, an individual subjects themself to physical ailments, since the act is deemed by him to be "unnatural". He also recommended a specific diet and to abstain from taking medications that were believed to enhance sexuality as a means to treat sexual impotence.

as an art that aims to contribute to the rise of a country. Furthermore, he mentions five separate sources that play into the overall outcome of politics. These include the tangible cause as corresponding to the subjects' affairs, the official reason as to the overall well-being of the people, the driving force as "the ruler’s concern for the affairs of his subjects", the purpose as the preservation of public welfare, as well as the instrumental cause consisting of using "incitement and intimidation" to achieve the goal.
