I recently came across a very useful and fun set of experiments created by a guy named Doug Harding that have value towards gaining further insight.

As with all successful insight practice, it is important to set aside pre-conceived notions of reality, and actually try the experiments with curiosity, fun, and an investigative spirit.

Here is the original work...

This particular experiment here, inspired by Harding but created by someone else, triggered some shifts in my understanding.

The way they actually help one attain realization is quite ingenious, in that they use everyday life pointing to challenge underlying mental views of reality.

If you are interested in spiritual enlightenment, I highly reccomend taking a few minutes out of your day to give these are try!

I'd never heard of the guy before but I really like his approach. I wondered if we could get Douglas to come by and contribute some stuff about his approach on here, but then I realized he died in 2007 and I had to edit this sentence. Ha!

Thanks for posting it!
