Read very slowly over a period of months so as better to take in the ideas and the connections between them. Admittedly I struggle a lot with maintaining equilibrium and remaining mindful, but eventually things do sink in. I found this a pretty solid intro as to the ordering and inter-relationships of important concepts in Buddhist thinking. So much of this comes back to mindfulness and being in the moment.
Recommended. I know I'll be keeping this by my bedside to return to. In the meantime... breathe.
