I might be doing it wrong.
When I do it I discovered a new form of concentration which require total absence of effert
I can only do it for a few seconds
it is so extyremely hard to maintain this relax state
but I can do so much in those seconds
am I doing it wrong?
I will tell you the one my father taught me.
Dim the light and lie still in a quiet comfortable place.
Pay attention very closely to the feeling of one toe.
After a while you will be able to feel your pulse in your toe.
At this point shift focus to another toe and repeat.
When you have felt the pulse in each toe you will have been absolutly quiet and still for fifteen minutes without realy noticeing the passage of time .
If you are still awake , try to feel your pulse in your feet and legs , fingers and where ever elese .
The pulse feeling is always there , but it is a tiny thing that is never noticed without either an unusually strong pulse or a very strong concentration of attention.
