Every day the Book of Nature lies open before your eyes, and from it you can learn the wonders of eternal wisdom engraved by the Creator

"Every day the Book of Nature lies open before your eyes, and from it you can learn the wonders of eternal wisdom engraved by the Creator on each stone, on each flower and on each star. Why is it that you do not understand them? Why is it that your eyes are not able to see or your ears to hear? Because you are too busy with useless and even harmful activities that prevent it. You will say, 'But these activities please us.' Yes, unfortunately, they please you; but everything that pleases you is not automatically good for your evolution. When you decide to sacrifice some unhealthy pleasures, you will release wonderful energies: your eyes and ears will open, and the Book of Nature will reveal itself to you.
When you are faced with certain problems in life, you say, 'Why can't I understand? Other people understand but not I!' Answer that question yourself, 'It is because I still look for inferior pleasures, which undermine my energy. That is why there is none left for my inner ears and eyes.' There is no other explanation for your inability to understand. You have to release energies so that they may awaken your spiritual centers on higher levels."
