No claims were made by him [Buddha] to any unalterable truth, nor did he demand that his teachings should simply be accepted, taken on trust or acquired through an act of faith. Instead he [Buddha] encouraged those who wished to make the spiritual journey he himself had undertaken to experiment for themselves as individuals, retaining what was useful to them and abandoning what was not.
