" The tensions between Gotama and the Buddha and between the dharma and Buddhism may have started during Gotama’s lifetime. The discourses themselves provide ample examples of how Gotama was transformed from a human being into a quasi-deity, and the dharma was transformed from a practical ethics into a metaphysical doctrine. The texts that make up the early canon cannot, therefore, be regarded as sharing an equivalent antiquity, but need to be understood as products of the doctrinal and literary evolution of a tradition that took place over at least three centuries.
