Our allegiance is to the principles always, and not to the persons. Persons are but the embodiments, the illustrations of the principles. If the principles are there, the persons will come by the thousands and millions. If the principle is safe, persons like Buddha will be born by the hundreds and thousands. But if the principle is lost and forgotten and the whole of national life tries to cling round a so-called historical person, woe unto that religion, danger unto that religion!
Swami VivekanandaHinduism threw away Buddhism after taking its sap. The attempt of all the Southern Acharyas was to effect a reconciliation between the two. Shankaracharya's teaching shows the influence of Buddhism. His disciples perverted his teaching and carried it to such an extreme point that some of the later reformers were right in calling the Acharya's followers "crypto-buddhists".
Swami VivekanandaMark, therefore, the ordinary theory of practical religion, what it leads to. Charity is great, but the moment you say it is all, you run the risk of running into materialism. It is not religion. It is no better than atheism - a little less.
