Gate Keeper? Ain't got one, personally. I also don't always work the chakras during meditations...in fact, I RARELY do.
To me, meditation is a state of ....regeneration and reflection or the doorway to Astral. It may not be the same for everyone, and I'd be very surprised if it was. Since meditation is the sphere of the subconscious mind, and everyone's minds are different, what you experience isn't going to be like what someone else does. I don't usually see fields during meditation; I usually see a forest. That's me, and probably because I am more comfortable in a forest on some mountain than anywhere else. When I see other vistas, it's because I have something to learn.
