[Star Wars] In the Empire Strikes Back, Luke brings his weapons with him to the cave that is strong with the Dark side, and "fails" the test. What would have happened if he had left his weapons behind?

Luke finishes his day's training with Yoda, and they're talking about the Dark side.  Luke put on his jacket, but he feels cold.  He goes to investigate, and Yoda points out that a particular place is strong with the Dark Side.  Luke goes to investigate grabbing his weapons on his way - as he does so, Yoda says "Your weapons, you will not need them", but Luke carries on.

In the cave, Luke comes face-to-face with Darth Vader (in a tunnel with surprisingly straight walls - is this an old Sith temple?), and when he strikes Vader down, the mask blows off to reveal Luke's own face - a harbinger of what is to come should Luke succumb to the Dark Side.  But what would have happened if Luke had left his light sabre behind?  Would he and this vision of Darth Vader just had a chat?  Would he have seen something else entirely?  What is Yoda hiding on Degobah?

Luke went in itching for a fight, and the cave showed him what that attitude would get him.

It wasn't as much about physically taking his weapons into the cave as it was mentally doing so.

The cave, in Legends, had a long and storied history of conflict between Jedi and dark side users, leaving an imprint on it. It's not a hidden temple or anything like that, just a place with a lot of bad memories. The only thing Yoda was hiding on Dagobah was himself.
