Do not encumber your mind with useless thoughts. What good does it do to brood on the past or anticipate the future? Remain in the simplicity of the present moment.
Dilgo Khyentse RinpocheTo expect happiness without giving up negative action is like holding your hand in a fire and hoping not to be burned. Of course, no one actually wants to suffer, to be sick, to be cold or hungry - but as long as we continue to indulge in wrong doing we will never put an end to suffering. Likewise, we will never achieve happiness, except through positive deeds, words, and thoughts. Positive action is something we have to cultivate ourselves; it can be neither bought nor stolen, and no one ever stumbles on it just by chance.
Dilgo Khyentse RinpocheTo feel overflowing love and almost unbearable compassion for all living creatures is the best way to fulfil the wishes of all the Buddhas and Bodhisattvas. Even if for the moment you cannot actually help a sentient being in an external way, meditate on love and compassion constantly over the months and years until compassion is knit inseparably into the very fabric of your mind.
Dilgo Khyentse RinpocheSentient beings, self and others, enemies and dear ones-all are made by thoughts. It is like seeing a rope and mistaking it for a snake. When we think that the rope is a snake, we are scared, but once we see that we are looking at a rope, our fear dissipates. We have been deluded by our thoughts. Likewise, mentally fabricating self and others, we generate attachment and aversion.
