I would like to bump this because after reading the article that SPRINGJ posted, I am actually scared to try the Small Universe now. The article appears to be written by someone with much experience and cautions that people have not only done damage to themselves by practicing the Small Universe prematurely, but have even ended up in the hospital.

Can anyone comment on why there is no need to have these fears? Perhaps the Spring Forest method is different than other Small Universe meditations and more suited to beginners?
