The truth is where you find it, & once you have found it in one place, it is still the same truth wherever you go. And when you go where you go & look around, if truth is there you recognize it. If you don't recognize it, it isn't there.
The holy texts of all cultures contain the descriptions of truths beheld. As there is at the base of 'All Truth', a single 'Truth', one has to wonder why these texts are so long. It is because seeing the truth - or knowing the truth if you will - is not the same as describing the truth.
The truth is available to everyone & they may know it without having others show it to them. We call this occurence the 'epiphany'. The child's self-relization 'hey, I can stand up', is just one such example of 'epiphany'.
Krisna is very patient in explaining to Arjuna how the truth works in order to force him to conclude he must fight.
