"From this moment onwards
Until i attain enlightenment,
I shall not harbor harmful thoughts,
Anger, avarice or envy"
"I shall cultivate pure conduct,
Give up wrong-doing and desire
And with joy in the vow of discipline
Train myself to follow the Buddhas"
A bodhisattva vows to benefit all beings and lead them to enlightenment. Harming others in thought, word, or deed would contradict this vow, so a bodhisattva forswears them. Virtuous conduct is the root of all attainment on the bodhisattva's path, so an aspiring bodhisattva cultivates positive qualities and abandons negative ones.
