“The more closely one studies Nietzsche's work, the less inclined one is to look outside it for an elucidation of its meaning or an explanation of its origin.”

Ananda Coomaraswamy, Hinduism and Buddhism
Context: The more superficially one studies Buddhism, the more it seems to differ from the Brahmanism in which it originated; the more profound our study, the more difficult it becomes to distinguish Buddhism from Brahmanism, or to say in what respects, if any, Buddhism is really unorthodox. The outstanding distinction lies in the fact that Buddhist doctrine is propounded by an apparently historical founder, understood to have lived and taught in the sixth century B. C. Beyond this there are only broad distinctions of emphasis. It is taken almost for granted that one must have abandoned the world if the Way is to be followed and the doctrine understood.... but nothing could be described as a 'social reform' or as a protest against the caste system. The repeated distinction of the 'true Brahman' from the mere Brahman by birth is one that had already been drawn again and again in the Brahmanical books.

(original Dutch: citaat van Willem Roelofs, in het Nederlands:) Maak dan die studies buiten; met de grootste eenvoudigheid, tracht u van alle zogenaamde manier te ontdoen en tracht in een woord de natuur met gevoel maar zonder denken aan het werk van anderen, na te volgen.
Quote in Roelof's letter to his pupil Hendrik W. Mesdag, 1866; as cited in Zó Hollands - Het Hollandse landschap in de Nederlandse kunst sinds 1850, Antoon Erftemeijer https://www.franshalsmuseum.nl/wp-content/uploads/2017/12/zohollands_eindversie_def_1.pdf; Frans Hals museum | De Hallen, Haarlem 2011, p. 16, note 7
