"The most important factor in maintaining peace within oneself, in the face of any
difficulty, is one's mental attitude. If it is distorted by such
feelings as anger, attachment or jealousy, then even the most
comfortable environment will bring one no peace. On the other hand, if
ones attitude is generally calm and gentle, then even a hostile
environment will have little effect on ones own inner peace. Since the
basic source of peace and happiness is ones own mental attitude, it is
worthwhile adopting means to develop it in a positive way.
~ Dalai Lama
