I've never understood the appeal of low doses. I have a friend who loves ket but has never even holed. He just takes tiny little lines every hour or so. To me thats a waste of good ket. It's mildly relaxing, but there are better drugs for that purpose such as benzos.
I prob buy a gram every 6-12 months or so, and circumstances permitting, usually take it all in 2 days max. Anytime i try a new batch I do a 100mg line to guage potency. This isn't usually quite enough to hole but certainly lets me know what i'm working with. A couple of hours later I try again. Usually it takes about 150-180mg.
The first thing to happen is a sense of movement, and thats when I know i'm along for the ride. It feels just like being on a toboggan or sledge, flying down vast sand dunes, down underground, down and then.. Into a different place. I like to have either an enlightening lecture or some music on as it really seems to guide the experience. My go to k holing song is Jimi's 1983... A Merman I Should Turn To Be. The song is a psychedelic journey of itself. When I talk about entering a different place, what I mean is that I feel like I have probably died and it feels impossible that I could ever find my way back to my body. It feels like the dimensions fold inwards and I see my daily life and the life of the universe as an experiment by all of creation to narrow experience down, like bill hicks said, "the universe experiencing itself subjectively". It's obvious in that space that time is illusory. Another thing that seems obvious there is that non-existence is impossible. We are all fragments of an eternal god and will return there after a few trips around the sun..only to begin again. It's sounds nihilistic but I don't mean it that way. I don't know if the Buddhists are right about karma, but these experiences make me feel that we should strive to be better, to do right, that it matters. Harm to others is harm against the self and vice versa. Anyway, thats what I see as the appeal of k holing.
