Name any two types of sources through which we come to know about the Buddha and his teachings.
The two sources are:
(i) Buddhist Texts: We can know about the Buddha's teachings through the Buddhist-texts. These have been reconstructed by carefully editing, translating and analysis.
(ii) Historians have also tried to reconstruct details of his life from hagiographies. Many of these were written down at least a century after the time of the Buddhist, in an attempt to preserve members of the great teacher.
