If we want to understand pañca(upādāna)khandhā we need to recognize it in every experience. But since we do experience time and have sense of time, I cannot see why the Dhamma, i.e. the full understanding of it, should be as the second after time. Therefore Dhamma is akalika, t.i. dhammas, which are explained by the Buddha, are the factors of the structure of our experience. And since p.s. is also part of experience, p.s. becomes akalika too.
A bit about it can be found also at http://pathpress.wordpress.com/2013/03/ ... n-an-1-51/
and http://pathpress.wordpress.com/2010/12/ ... h-applies/
and of course this topic is explained in Ven. Nanavira's writings but I am sure you know where to look at.
Anyway, as usual, it will be confirmed by all the same people and rejected by the other. But my main point is here: don't take it as a easy matter.
