Hi Migwell,I love discussing the effects of the four techniques- because, when you remove the bullshit and belief system, that's all that's left.
My experience, (exactly the same as when I used to be a guru toe kisser)-
I see pretty shiny patterns when I press my eyes.
I feel my breath going in and out of my lungs.
I hear a sound like listening to the sea in a seashell (though not quite as good)
I taste spit and snot at the back of my mouth.
Anything added to that is pure imagination, conjecture, hope and faith.
Anth the snot gobbler.
