Buddhism is both a religion and a philosophy. This religious sentiment, deeply imbued in the hearts of people, often causes them to fabricate historical reality and render supernatural effects to symbolic happenings. Therefore, to rely solely on historical facts without any sense of empathy, one will certainly fail to attain the Truth.
Philosophy involves an attainment of Truth in a precise and meticulous manner. The wisdom of ancient philosophy remains naive yet cautious in thinking, and direct in argument.
Their language is usually simple yet profound, and uses relevant examples that embody deep thinking. Therefore, to only seek for the validation of textual evidence without any spiritual attainment, one will only gain what is as good as dregs.
