“Bodhicharyāvatāra”
by Shantideva
Chapter 5, Attentiveness:
71.
Be the master of yourself
And have an ever-smiling countenance.
Rid yourself of scowling, wrathful frowns,
And be a true and honest friend to all.
“The Bodhisattva Guide”
commentary by H.H. The Dalai Lama:
“True practitioners are unaffected by external pressures and their own emotions, and they are free to secure the temporary and ultimate benefit of both themselves and others. They remain independent, fear nothing, and are never at odds with themselves. Always peaceful, they are friendly with all, and everything they say is helpful. Wherever we go, let us be humble and avoid being noisy or bossy. Let us not hurt other people’s feelings or cause them to act negatively. Rather, let us be friendly and think well of others, encouraging them to accumulate positive actions….”
“Whatever we say, let us speak clearly and to the point, in a voice that is calm and pleasant, unaffected by attachment or hatred. Look kindly at others, thinking, it is thanks to them that I shall attain Buddhahood.”
On Practice of Compassion:
Compassion for those you love and who love you comes naturally.
For those who you would judge or would judge opportune for practice.
Practice compassion for all until self-nature.
