If meditation is producing some negative effect, stopping the meditating usually stops the problem.
The "usually" is really imortant. If the problem you're dealing with is altered states of consciousness, then yeah, stopping the meditation ought to solve the problem. But if you're dealing with the fruits of significant insight then too bad; there is no going back.
Yeah, I'm talking about covering appliances' small indicator lights, because gaff tape alone allows light to shine through.
use tin-foil
I do this too to block out light.
Kensho is insight. Enlightenment is the fruit of insight. Kensho is a state of consciousness that provides insight into your world model. Enlightenment/awakening typically comes from having a world model that has (usually) been modified via such states of consciousness (and other thinngs).
What you want to avoid are temples, churches, and missions.
Note: The Zen practice center I go to is officially listed on Google Maps as a "temple" even though it's not really a temple (the way Gordon is using the word "temple").
This is a good idea for a separate post.
This is good advice, especially "pay attention for a feeling of coming home".
I'm tempted to recommend books too, but all of them come with tradeoffs.
That looks to me like an accurate description of kensho, which is a taste of enlightenment. It indicates you're going in the correct direction and is a good source of insight.
I haven't asked.
Insight doesn't act on the conceptual level, it acts on the perceptual level. It's like noticing that you've got a rock in your shoe. Doing violence to the part of your brain that notices the rock in your shoe is just going to draw more attention to that area of neural activity.
