"the greatest gift of our century", and predicted that the philosophy and knowledge of the Upanishads would become the cherished faith of the West. Most noticeable, in the case of Schopenhauer's work, was the significance of the Chandogya Upanishad, whose Mahāvākya, Tat Tvam Asi, is mentioned throughout The World as Will and Representation. Buddhism Schopenhauer noted a correspondence between his doctrines and the Four Noble Truths of Buddhism. Similarities centered on the principles that life involves suffering, that suffering is caused by desire (taṇhā), and that the extinction of desire leads to liberation. Thus three of the four "truths of the Buddha" correspond to Schopenhauer's doctrine of the will. In Buddhism, while greed and lust are always unskillful, desire is ethically variable – it can be skillful, unskillful, or neutral. For Schopenhauer, will had ontological primacy over the intellect; desire is prior to thought. Schopenhauer felt this was similar to notions of puruṣārtha or goals of life in Vedānta Hinduism. In Schopenhauer's philosophy, denial of the will is attained by: personal experience of an extremely great suffering that leads to loss of the will to live; or knowledge of the essential nature of life in the world through observation of the suffering of other people. Buddhist nirvāṇa is not equivalent to the condition that Schopenhauer described as denial of the will. Nirvāṇa is not the extinguishing of the person as some Western scholars have thought, but only the "extinguishing" (the literal meaning of nirvana) of the flames of greed, hatred, and delusion that assail a person's character. Schopenhauer made the following statement in his discussion of religions: If I wished to take the results of my philosophy as the standard of truth, I should have to concede to Buddhism pre-eminence over the others. In any case, it must be a pleasure to me to see my doctrine in such close agreement with a religion that the majority of men on earth hold as their own, for this numbers far more followers than any other. And this agreement must be yet the more pleasing to me, inasmuch as in my philosophizing I have certainly not been under its influence [emphasis added]. For up till 1818, when my work appeared, there was to be found in Europe only a very few accounts of Buddhism. Buddhist philosopher Keiji Nishitani sought to distance Buddhism from Schopenhauer. While Schopenhauer's philosophy may sound rather mystical in
