The plan is to meditate until I experience a form that is foreign to me.
I filled a bucket with about 30 liters of gypsum plaster and 30 liters of water. I whipped it together so it would harden faster. I then sat down in front of the lump and began to meditate.
After about 90 minutes, I found that the thought of a specific form "insisted" in my mind so I concluded the meditation.
