Massage
One of the greatest Persian medics was Avicenna, also known as Ibn Sina, who lived from 980AD to 1037AD. His works included a comprehensive collection and systematisation of the fragmentary and unorganised Greco-Roman medical literature that had been translated Arabic by that time, augmented by notes from his own experiences. One of his books, "Al-Qānūn fī aṭ-Ṭibb" (The Canon of Medicine) has been called the most famous single book in the history of medicine in both East and West. Avicenna excelled in the logical assessment of conditions and comparison of symptoms and took special note of analgesics and their proper use as well as other methods of relieving pain, including massage.
Philosophy of happiness
Avicenna (c. 980–1037), also known as 'Ibn-Sina', was polymath and jurist; he is regarded as one of the most significant thinkers in the Islamic Golden Age. According to him, happiness is the aim of humans, and that real happiness is pure and free from worldly interest. Ultimately, happiness is reached through the conjunction of the human intellect with the separate active intellect.
