laying down with a bucket is a good start...
lightly toast the seeds, powder them..mix with calcium hydroxide or carbonate, add a little water and mix it around to raise the ph..let it dry..add some harmalas power/mix it all up...and then snuff.
That is my recipe. 1-2 seeds is a good place to start if they are potent. If you only get physical side effects and no visions, take more. The side effects can be so bad you might want to never take more or try it again, but trust me, there is a point at which this snuff can be about the most visual entheogen I have encountered. You just have to get the dose right and breath through the side effects.
