Verses 7-9 of 27 Verses on Mind Training

7) The seeds of action are positive and negative intentions. Any intention consciously rooted in selfless motivation, desiring only sheer goodness for all conscious life, will establish the stable ground of goodness and will universally generate rich results of goodness. Any intention even slightly weakened by selfish motivation undermines both the ground of our life and its fruits. Intention is the sole creative force of existence.  

8) To cling to the intention of triumphing over another, the desire to prosper at the expense of any being or to indulge in the slightest bias against any being because of personal feelings of attraction or repulsion, these alone are the causes for whatever suffering exists in personal lives and in the universe as a whole. We should meditate ceaselessly on this revolutionary truth, remaining conscious of it during every moment of existence. 

9) Those who attempt to deceive with words of advice that in any way exalt selfishness and depreciate selflessness become hopelessly lost in narrow-mindedness, obsessed with their own selfish interests. Such persons create the only error in the universe: diverting our precious care and concern for others to ourselves. This deception not only expresses hatred for Buddha’s wisdom but is the absurd attempt to destroy universal Buddha nature.
