Out of the three marks of existance, 'dukkha' or 'sufferring' and 'annicca' or 'impermenance' are directly understood as a day-to-day experience as well as through the intellect.
However 'anatta' or 'no-self' is neither a normal day-to-day experience nor can it be intellectually understood.
I know that in the first Jhana, 'anatta' is a direct experience, but for those who have not yet reached the state of Jhana how can one cultivate the perception of 'anatta' such that it helps to move towards Jhana? How can one be mindful of 'anatta' off the cushion?
