- Important readings in vipassana 2 answers
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?
