Born out of agitation is thought’s habitual nature of predicting, based solely on past knowledge. It uses the past to predict the future. This agitation is thought’s tendency to deny the living present, being stuck on the past and/or projecting into the future.
Now, one may wonder, “How to end this?” It cannot be ended, however, once this agitated state of thought is observed it goes into abeyance. The activity itself persists but YOU, that point of observation, ceases being flung to and fro thoughts projection into the past or future.
Obviously thought itself is contradiction, but, there are different modes of thought in its movement. Normally thought flings into the mind upon waking perception, perceiving an object. The past begins to articulate itself based on this. That is its first movement. Depending on the situation, thought moves variously in accordance with the particular situation. An example of this is analysis vs. instinctual action. For instance, one who is analyzing facts and historical documents is undergoing a slower movement of thought, whereas, one who is in the midst of danger acts immediately (either ‘fight or flight’ response) because thought is moving in a unitary sense.
This unitary movement of thought is far quicker than the sluggish searching action of thought that is based in analysis.
