Try meditating for 24 hours in a row. Something "interesting" is bound to happen - most likely severe pain somewhere in the body. If you were able to observe that pain objectively with equanimity, meaning a) not averting from an experience you don't like or b) craving to have an experience you do like, wisdom about the nature of reality arises spontaneously. More specifically, pain is not really what you think it is - some experience to shun worth avoiding at all costs. Watching the mind react to such an experience, and there are so many experiences that the mind is nearly hardwired to avert from or cling to, speak volumes. You will see how desperate it wants to stay in control of your experience and you should also note that because you can observe your mind, YOU ARE NOT YOUR MIND. Now you are starting to inquire into the nature of reality as-it-is, not as you want it to be. Yes, you can sit against a wall.
