I have found harmalas to have a quieting effect on the mind and a reasonably good addition to long meditation sessions. Most of my meditation happens in 15 minure blocks, while sober and eyes closed. I have a hard time meditating with eyes open and I wonder how much a difference it really makes. To those of you who keep your eyes open: what's the difference?

I have found it very difficult to meditate with LSD or cannabis. I have had limited success using LSD during meditation and have found cannabis to be completely counterproductive. I have enjoyed kava before meditation as well.
