A seeker of truth will never begin by discounting his opponent's statement as unworthy of trust.
The seeker after truth should be humbler than the dust. The world crushes the dust under its feet, but the seeker after truth should so humble himself that even the dust could crush him. Only then, and not till then, will he have a glimpse of truth.
The seeker is at liberty to extract from this treasure any meaning he likes, so as to enable him to enforce in his life the central teaching.
