Vipassana texts and books references request I just read Allan Wallace's "The Attention Revolution: Unlocking the Power of the Focused Mind" book. He cites vipashyana (or vipassana, vipassanā, vipaśyanā, lha-thong) but he doesn't deepen much on it.

Can you refer to some texts and books regarding this meditation?
Buddhanet contain a lot of meditation related ebooks on the topic which you can read. A good introductory book would be:


Essentials of Insight Meditation Practice
MINDFULNESS IN PLAIN ENGLISH
Right Mindfulness: Memory &amp; Ardency on the Buddhist Path
