What does "allow" mean here?

"Allow" in this case means to "let" or to "permit" something to happen. So in the context of the video here, he means that they should "allow" or "let" the happiest memory they can remember fill them up, or take control. Ex: She doesn't allow her children to watch T.V. Ex: I have many fears, but I don't allow them to stop me.
