As long as the mind is unsubdued, there is always outside harm. Once the mind is subdued, once there is no anger in the mental continuum, there is no outside enemy. An outside enemy exists only if there is anger inside.
Thubten Zopa RinpocheWhenever you hear that someone else has been successful, rejoice. Always practice rejoicing for others-whether your friend or your enemy. If you cannot practice rejoicing, no matter how long you live, you will not be happy.
Thubten Zopa RinpocheWhen? At this time, while you have all the opportunities, if you do not do your best to achieve the pure, stainless path to enlightenment when will you do it? If you don't meditate, don't practise the graduated path to enlightenment, especially bodhicitta, in this life, then when? When will you practise? When will you have this realization? If, in this life, you don't achieve renunciation, bodhicitta and sunyata, as well as the two stages of tantra, when will you? When will you have these attainments? When will you become enlightened? When will you perform perfect work for sentient beings?
