Stand and check the limits of your sight up down and to the sides. Avoid missing what you do not see behind under or above and check for reflective and shadow surfaces and movements to inform you of something out of your direct sight. tense and relax your face and eyes and see if that helps you seem more in any way. Sit down in the same spot you were standing and note what you gain and what you loose from this vantage point. Check if your neck is relaxed or is your posture sacrificing something for something else. Lie down in the same spot and again work on what you can see more now and what is no longer in your direct sight. Avoid having your own body in the way of your sight such as pointing arms or loose garments and hair if you have any and consider how you can use what you have amassed to create a more true and complete understanding of the situation. Have you now more knowledge of the shadows and mirrors and the structure of what is around you. Does tensing the eyes and face aid in getting more information. Does tensing the neck help in any way.
