Below is a wonderful description by the poet Ted Hughes, of the meditative state that you can slip into when float fishing.
Settling the mind is a valuable thing to be able to do – but something you are never taught in school and not many people do it naturally. I am not very good at it, but I did acquire some skill in it. Not in school, but while I was fishing. I fished in still water, in those days, with a float. As you know, all such a fisherman does is stare at his float for hours on end. I have spent hundreds and hundreds of hours staring at a float – a dot of red or yellow the size of a lentil, ten yards away. Those of you who have never done it, might think it a very drowsy past time. It is anything but that.
All the little nagging impulses, that are normally distracting to your mind dissolve. They have to dissolve if you are to go on fishing. If they do not, then you cannot settle down: you get bored and pack up in a bad temper. But once they have dissolved, you enter one of the orders of bliss.
Your whole being rests lightly on your float, but not drowsily: very alert, so that the least twitch of the float arrives like an electric shock. And you are not only watching the float. You are aware in a horizonless and slightly mesmerized way, like listening to the double bass in orchestral music, of the fish below there in the dark. At every moment your imagination is alarming itself with the size of the rings slowly leaving the weeds and approaching your bait. Or with the world of beauties down there, suspended in total ignorance of you. And the whole purpose of this concentrated excitement, in this arena of apprehension and unforeseeable events, is to bring up some lovely solid thing, like living metal, from a world were nothing exists but those inevitable facts which raise life out of nothing and return it to nothing.
