Whenever we study the Dharma or do any Dharma practice, the most important thing is to have a pure motivation. If we have a pure motivation, whatever we do with our body, speech, and mind will turn out well. But if our motivation is not pure, then even if what we do with our body, speech, and mind seems good from the outside, it will actually not turn out well in the end. Just starting to read in this server shows that you want to learn about the Dharma and to practice it; it demonstrates that you have some faith and devotion. This is a good motivation, but it is important to have a truly vast motivation-the motivation of bodhichitta. Sometimes our motivation is influenced by our afflictions, and if that is the case, then we should get rid of such a motivation. Sometimes our motivation is not in any way afflicted or negative, but it is possible that it is just a wish to help ourselves. There is nothing terribly wrong about that sort of motivation, but it is very limited, and so this also is a motivation that we should give up. Instead we should have the motivation to bring benefit to all of our former mothers and to all the sentient beings of all six realms of samsara who are as limitless as space. It is for their benefit that we practice the Dharma. It is for their benefit that we need to study the Dharma, so please read these teachings with the pure motivation of bodhichitta. This is the best reason to practice the Dharma.

~by Khenchen Thrangu in Vivid Awareness: The Mind Instructions of Khenpo Gangshar

Each instant, put your heart into it again.

Each moment, remind yourself again.

Each second, check yourself again.

Night and day, make your resolve again.

In the morning, commit yourself again.

Each meditation session, examine mind minutely. 

Never be apart from dharma, not even accidentally. 

Continually, do not forget.

~Patrul Rinpoche
