It's difficult to explain if you haven't had that kind of experience yourself, but one way to describe it is that psychedelics (some more so than others) open up a window that allows for change. You are no longer stuck in your old ways of thinking that you took for granted.
But the experiences themselves don't change you. You still need to put in the work to make the changes. You can certainly do this without a guide. But if you take these drugs recreationally without such intentions and without putting in hard work pre- and post-session, nothing much is going to happen in the long term. A guide will help you to get the most out of the experience (while also helping with trip safety).
It's not about whether you use psychedlics or not, it's about how you take them.
