If you observe nature at work, you will see that least effort is expended. Grass doesn't try to grow, it just grows. Fish don't try to swim, they just swim. Flowers don't just try to bloom, they bloom. Birds don't try to fly, they fly. This is their intrinsic nature. The earth doesn't try to spin on it's own axis; it is the nature of the earth to spin with dizzying speed and to hurtle through space. It is the nature of babies to be in bliss. It is the nature of the sun to shine. It is the nature of the stars to glitter and sparkle. And it is the human nature to make our dreams manifest in to physical form, easily and effortlessly.
