In summary, the solution to the puzzle is to ask one of the guards, "What would the other guard say if I asked them who you are?" The response will determine who is the truth teller and who is the liar.

Would he say that you are lying?

you ask either guards:
if i ask the other guard which door leads to freedom what door would he say?
they will show you the same door. you go to the other door.
the point is that the liar will point to the door of the tiger and so would the truth teller.

Sorry to be totally dead-pan about this.
The answer is a Double Negative.
If you ask the Truthful man what the other man will say he will say what the Liar would say.
If you ask the Liar what the Truthful man would say he will say a Lie, ie the opposite of the Truthful man.
The question therefore is: "If I ask the other man what is the gate/door to life/freedom, what will he tell me" - whatever the answer you do the opposite, because both men will tell either a Lie or a Truthful Lie.
The question must be a Double Negative !
