The Final Cause for all things is Abstract Intelligence. In its unconditioned state it remains still and undisturbed. In this state, the smallest intention has an effect like a small pebble being thrown in still water, the ripple spreads out evenly over its surface; easily manifesting a wide reaching effect.
Your intention is not making a splash because the surface of your mind is not still, therefore lost. Imagine throwing your little pebble into the roaring ocean.
First, calm the sea of your mind by turning away from desire to seek experiences in the senses and the fulfillment of thought; drawing all energy to the center. It is the constant grasping into the waters of human consciousness that causes waves and disturbances.
See the irony. One must seek the end of desire first and have an earnest dispassion for all outward things. Only then is one fit to command and manifest outward things with ease.
