Comparison to Eastern philosophies
Similarities between Spinoza's philosophy and Eastern philosophical traditions have been discussed by many authorities. The 19th-century German Sanskritist Theodore Goldstücker was one of the early figures to notice the similarities between Spinoza's religious conceptions and the Vedanta tradition of India, writing that Spinoza's thought was "... a western system of philosophy which occupies a foremost rank amongst the philosophies of all nations and ages, and which is so exact a representation of the ideas of the Vedanta, that we might have suspected its founder to have borrowed the fundamental principles of his system from the Hindus, did his biography not satisfy us that he was wholly unacquainted with their doctrines... We mean the philosophy of Spinoza, a man whose very life is a picture of that moral purity and intellectual indifference to the transitory charms of this world, which is the constant longing of the true Vedanta philosopher... comparing the fundamental ideas of both we should have no difficulty in proving that, had Spinoza been a Hindu, his system would in all probability mark a last phase of the Vedanta philosophy."[18][19]
It has been said that Spinozism is similar to the Hindu doctrines of Samkhya and Yoga. Though within the various existing Indian traditions there exist many traditions which astonishingly had such similar doctrines from ages, out of which most similar and well known are the Kashmiri Shaivism and Nath tradition, apart from already existing Samkhya and Yoga.[20]
Max Muller, in his lectures, noted the striking similarities between Vedanta and the system of Spinoza, saying "the Brahman, as conceived in the Upanishads and defined by Sankara, is clearly the same as Spinoza's 'Substantia'."[21] Helena Blavatsky, a founder of the Theosophical Society also compared Spinoza's religious thought to Vedanta, writing in an unfinished essay "As to Spinoza's Deity – natura naturans – conceived in his attributes simply and alone; and the same Deity – as natura naturata or as conceived in the endless series of modifications or correlations, the direct outflowing results from the properties of these attributes, it is the Vedantic Deity pure and simple."[22]
