This quote from Ajahn Chah might be helpful in Chapter 4 of ''The Island - An Anthology of the Buddha's Teachings on Nibbana'' by Ajahn Pasano and Ajahn Amaro

The Buddha talked about sankhata dhammas and asankhata dhammas - conditioned and unconditioned things. Conditioned things are innumerable - material or immaterial, big or small - if our mind is under the influence of delusion, it will proliferate about these things, dividing them up into good and bad, short and long, coarse and refined.

Why does the mind proliferate like this ? Because it doesn't know conventional determinate reality, it doesn't know about conditions. Not knowing these things, the mind doesn't see the Dhamma. Not seeing the Dhamma, the mind is full of clinging. As long as the mind is held down by clinging, there can be no escape from the conditioned world....

Asankhata dhamma, the unconditioned, refers to the mind that has seen the Dhamma, the truth of the five khandhas as they are - as transient, imperfect and ownerless. All ideas of 'me' and 'mine', 'them' and 'theirs' belong to the determined reality. Really they are all conditions.

When we let go of conditions we attain the Dhamma, we enter into and realise the Dhamma.
