This has five sections: (1) how morality is completely purified on this ground, (2) the praises of morality, (3) the analogy for how the bodhisattva does not mix with forces opposing morality, (4) the divisions of the perfection of morality, and (5) a conclusion stating the qualities of the ground.
How morality is completely purified on this ground
This has four parts: (1) showing that morality is perfected on this ground, (2) showing that on this basis the qualities become completely purified, (3) how morality becomes superior compared to the first ground, and (4) other causes that purify morality.
Showing that morality is perfected on this ground
He is endowed with perfect morality and purity;
even in dreams, he shuns the stain of immorality.
The bodhisattva abiding on the second ground — because he is endowed with the perfect morality as well as the qualities of purity, not only during his waking period but even in his dreams — shuns the stain of immorality; that is, he remains untouched by it.
Because he does not inflame the afflictions that give rise to immorality, and because the nonvirtuous karma of transgressing prescribed rules does not occur for him, he has attained the coolness borne of having extinguished the fires of remorse from accruing the downfalls of violating prescribed rules.
This is therefore called morality.
The Sanskrit term for morality is śīla, which is composed of the words śīta, referring to “coolness,” and lati, meaning “to attain.”
The underlying states of mind that give rise to these seven relinquishments are (1) nonattachment, which is the absence of covetousness, (2) nonaversion, which is the absence of harmful intent, and (3) right view, which opposes wrong view.
By including these motivating factors, morality refers to the ten relinquishments, ten positive courses of action that overcome the ten negative courses of action.
Since all movements of his body, speech, and mind are pure,
he accumulates the excellent virtue of all ten courses of action.
One might ask, “How do the qualities of this bodhisattva come to be purified because of his perfect morality?”
Since all his movements — the threefold activity of his body, speech, and mind — are pure, without even subtle downfalls throughout his waking and dream states, he accumulates, without omission, the sublime or excellent virtue of all ten courses of action.
To accumulate all ten courses means to fulfill the first three courses of action, such as relinquishing killing, through his body, the four middle ones through his speech, and the three final courses through his mind.
