Purification of the mental speech
If your mind is too agitated, you may try to replace words with purely algebraic expressions by replacing each and every word by X.
For instance, the sentence: the pine is a tree would become x x x x x
Since X can mean everything, the process of replacing words (nouns, verbs, adjectives, complements) with it purifies the content of the mind. This creates openness and helps remove limitations from the thinking process. It is however useless to add more X than there would be words in the first place. Once one achieve total replacement of words to Xs, one can start progressively reducing the amount of remaining X until the mind is quiet.
