Oddly, many of these are usually misinterpretations of America's favorite Buddhist discourse, the Kalama Sutra.
This is odd because it is exactly the "Message to the Kalamas" (AN 3.65) that suggests how to distinguish Dharma from non-Dharma, what would be good to accept as truth and what would be better rejected.
- When a great publication is the bad source of quotes (shoddy fact checking from Tricycle Magazine)
The only way to be sure if the historical Buddha, the "Sage of the Shakyas," said something is to look for the mark of legitimacy then check that citation against the texts.* In parentheses there should be a citation that refers to sutra's collection and location as in "AN 3.65," which means Anguttara Nikaya, "Numerical Discourse Collection" and its exact "address" within that collection of sacred texts.
- Buddha? Who is "Buddha"? In Mahayana Buddhism and Hinduism the name refers to countless bodhisattvas and deities. In Theravada and for careful readers, the title refers to the historical Buddha, Siddhartha Gautama, and to a very limited number (28) of historical buddhas he named and one future buddha he described (Maitreya). Those buddhas ("Supremely Enlightened Ones") are revered every month in Theravada temples, where each has a name and the aeons they lived and made known the path to freedom, the timeless Dharma that is always there to be rediscovered by anyone who develops the Ten Perfections (paramitas, reduced in Mahayana to six, just as the 31 Planes of Existence the historical Buddha outlined were reduced to six) with the intention of liberating others.
