In The Last Jedi, we get many scenes of Luke being generally negative towards the Jedi, The Force and pretty much everything.
In a later scene, Rey and Luke have a conversation in which Ray says the following and it appears, from Luke's reaction, that her assumption is correct.
Rey: You've shut yourself off from the force.
However, Luke still appears to be using the force in his daily routines. For example, he uses a spear pole to jump across a large gap and land on a very narrow ledge and then using the same pole spears a large fish, which appears to happen on his first try. It is then implied that he gets back across the gap using the same method, potentially with the fish.
Is there any evidence that he did completely shut himself off?
