brain states and jhana

[alan...]

anyone seen this? i have no idea if it's legit nor do i know a thing about the author:

http://www.kktanhp.com/samatha.htm

it seems to imply that the higher jhanas involve a brain state similar to sleep but with full consciousness? so could yoga nidra be possibly a perfect and exact supplementary practice to wakeful jhana practice?

not only that but perhaps this could also be a great leap for practitioners that struggle greatly with drowsiness? starting from a drowsy state and once you have that under control move in the other direction? as opposed to trying to relax and focus the mind without making it drowsy you're trying to make the mind drowsy but stay awake. if you believe the above article is legit, what do you think about the rest of my idea?

this is a little more in depth than the wiki page: http://www.swamij.com/yoga-nidra.htm#not

there are others such as this one I started a while ago to name one.
