Investigate yourself. Question everything. Take nothing for granted. Don’t believe anything because it sounds wise and pious and some holy men said it. See for yourself. That does not mean that you should be cynical, impudent, or irreverent. It means you should be empirical. Subject all statements to the actual test of your own experience, and let the results be your guide to truth. Insight meditation evolves out of an inner longing to wake up to what is real and to gain liberating insight into the true structure of existence. The entire practice hinges upon this desire to be awake to the truth. Without it, the practice is superficial.
