Para-Gram by Parmahansa Yogananda

The beauty of the sky and of all Nature makes a proper altar for the worship of the Infinite. This is God's world; and when you know the Master of this universe, He will show you all His wonders. In the airplane of your visualization and perception, glide over the vast tracts of fancy, scanning the limitless empire of your thoughts. Behold there the unbroken mountain ranges of lofty spiritual aspirations for self-improvement. Be guided by wisdom. Use judgment and discrimination. Remember, you are not the body, but the dynamic soul, the power of Spirit. Thus all knowledge and perception are within you. Feel yourself one with the universe, one with all nationalities, one with God.
