There are two ways for any object to move from one location to another, or to change from one state to another. Either the movement is created internally, or externally. The atomic bomb illustrates this form of internal movement: when an atom is split and releases vast sum of force. One object moves internally and then collides with another. We also view ourselves to be able to generate internally the source for our own movements. I decide to raise my arm and this thought causes a chain of electrical and chemical actions that eventually end with my arm moving. This movement is created and caused by an internal source.
The other means to cause objects to move is an external force at every point in space and at every moment in time. Without this expanding force, nothing moves, is static, unchanging, and stationary. This can be exemplified by a monitor screen in which the pixels do not move, do not change, are not turned on and off by themselves, but from an external force, a cable providing electricity to each pixel.
Thoughts do not have an internal source of power. A thought is dead, static, dormant, like a pixel, until some force stimulates it. A thought is dead, just like a word on a piece of paper, fixed, dead to the word next to it and after it. As otherwise, the thought, the word, will continue to move, to evolve, and to change. We move our words around. Our ideas, our sentences, are collections and strings of words in an organised pattern that which we understand and manipulate.
Personally, for me it is easier to visualise an expanding force at every point in space and at every moment in time. This is similar to a hypersphere in which inside the ball, the sphere (a 3-D object), is a fourth dimension and this fourth dimension leaks out into our 3D world at every point in space and at every moment in time.
Whichever view on the source of force you have, thoughts are still the objects in which the force stimulates, turn on. We do not observe this force. This movement. We observe only the objects. The end point of our desires, our emotions, our actions, and our patterns of living. These objects, those that are turned on, reflect the current state we are in. The picked and chosen objects are specifically selected from countless of other objects, choices, and actions, and become a reflection of us, as if we are looking at a mirror. We only see the objects, but not the force. We have made ourselves into viewing only the end and made our existence as if we are walking through a very narrow crevice. We think the world, our universe, our existence is at the end. Once we can view and experience the force, we would then see ourselves not walking through a very narrow crevice among steep mountains, but in a wide open field of beauty.
Is it not true that the best journey is not reaching the desired destiny, but the unplanned adventure on the way? We must move away from the pursuit of thoughts.
