" Sadhana Look around. Among your family, coworkers, and friends, can you see how everyone has different levels of perception? Just observe this closely. If you know a few people who seem to have a greater clarity of perception than others, watch how they conduct their body. They often have a certain poise without practice. But just a little practice can make an enormous difference. If you sit for just a few hours a day with your spine erect, you will see that it will have an unmistakable effect on your life. You will now begin to understand what I mean by the geometry of your existence. Just the way you hold your body determines almost everything about you. Another way of listening to life is paying attention to it experientially, not intellectually or emotionally. Choose any one thing about yourself: your breath, your heartbeat, your pulse, your little finger. Just pay attention to it for eleven minutes at a time. Do this at least three times a day. Keep your attention on any sensation, but feel free to continue doing whatever you are doing. If you lose attention, it doesn’t matter. Simply refocus your attention. This practice will allow you to move from mental alertness to awareness. You will find the quality of your life experience will begin to change. "
