Rawat specifically commanded us to not doubt and warned us incessantly of the hazards we'd face if we did. Don't be such a liar. 

Warning of the danger and commanding are two different approaches. I contend it was the former. And don't be so quick to call someone with a different POV a liar.

You're deep into Monty Python territory, mate.  Rawat called it a commandment and you can't even admit that.  Yes, you are a liar.  Despicable, in fact.   

But what if the directions are wrong? 

That is all the justification doubt needs. Now wallow in it!

I have gotten lost many times because I had this very same doubt.

Cut the sarcasm, mate. The fact is your own example backfires on you just like everything else you say.   

When is it okay to re-consider [the directions] or their source? 

There is no right answer to this question.

So therefore you have to think about the situation, right?  In other words, wonder if you got the right advice -- in other words, entertain doubts about it.  Checkmate as always, mate!

I'm afraid your example works far better in my favour than yours.

Not if the directions are accurate.

Sorry, we've already put this away. In order to know if the directions are accurate you have to think about it and consider the possibility they aren't.  In other words, doubt them.
