Obstacles can arise from good as well as bad circumstances, but they should never deter or overpower you. Be like the earth, which supports all living creatures indiscriminately, without distinguishing good from bad. The earth is simply there.
Your practice should be strengthened by the difficult situations you encounter, just as a bonfire in a strong wind is not blown out, but blazes even brighter.
Dilgo Khyentse Rinpoche
