Okay I have done 3 void meditations but they were all fairly similar, so I will post the longest and best one:

I was sick over the weekend so I was in bed most of the time. I lay down in my bed on my back with my arms on my side. I just waited for about a minute until some thoughts came. When they started to come I began to imagine placing them into a box. Because I practice this method so much, they never come back. After they began to come less frequently I started to count as I breathed deeply. Every deep breath in I imagined a clean light filling my body and every deep breath out would clean all bad stuff out. After doing this for about 5 minutes I began to keep breathing deeply without much on my mind. My body became heavy and I got some imagery. When I opened my eyes I felt extremely relaxed.
