Attempts at locating the Rubaiyat in Indian philosophical thought. A. Rangarajan.
In: The great ‘Umar Khayyám. Leiden, Leiden University Press, 2012. pp. 233–243.

In this article Rangarajan gives a metaphysical reading of Khayyám’s quatrains by comparing Khayyám’s description of human existence with the supernatural order of Hinduism. Moreover, the author concentrates on other religions such as Buddhism, Jainism and Ajivika, showing how Khayyám’s philosophy matches the tenets of these religions.
