C. The final summary

Therefore, abandon all the aspects of cause and fruition
That have a part in constructing formations of samsara.
But then you should produce with wholehearted diligence
The cause and fruition of the state of liberation.
By that the highest truth and goodness will manifest.
There will be the establishment of enlightenment.

Establish all virtues. Leave behind all evil deeds. The goal of life must be made to exist, since we should quickly go to it. The Friendly Letter says:

With many harms, this life is blown away on the wind.
If even a river of water is impermanent,
Exhaling and inhaling, when we go to sleep,
That we ever wake up again is really a miracle.

For that reason, to do evil to oneself and others is not suitable. To go so far as to do evil deeds for the sake of preceptors, masters, and the three jewels is ridiculous, since by that evil ripening wi thin us, we will not be able to participate in them. The same text says:

Practice virtue. For the sake of bhramans and gods,
For guests and fathers and mothers, queens and retinue,
Even for their sake, do not do evil deeds,
You will get no reward but ripening in Hell.

As for doing any sort of evil deeds,
If this is not cut off at once, as with a weapon,
When the time of death arrives, then there will manifest
The karmic fruit of all these various evil deeds.

Therefore, even with the elimination of evil actions, also it says:

As for the seeds of these unwholesome activities,
By purifying defilements of body, speech, and mind,
We should earnestly strive with all our present skill.
Not to create an atom of these for any reason,

This cannot be established by anything other than our own powers, by any association with others. Accepting good and rejecting evil must come from ourselves alone. Also it says:

As for liberation depending on ourselves,
It does not come from association with another.
If we have learning, discipline, and meditation,
Let us make an effort in the four noble truths.

As to how this should be done, it says:

O you master of reason, having so spent all the day,
And the first and final sessions of the night,
Even in your sleep not being without fruition,
Sleep between these sessions with mindfulness.

Always truly meditate on kindness and compassion,
As well as joyfulness and equanimity.
Even if it does not please superior ones,
May you attain the happiness of the Bhrama realms.

The happiness and sorrow of desiring and acting,
Completely being abandoned through practice of the four dhyanas,
May purity, radiance, and happiness increase,
And your fortune of fruition be equal to the gods.

Without conception, without attachment and antidotes,
Having the principal virtues of the four dhyana states,
As for the five great virtues and the five non-virtues,
Strive to perform the actions that are virtuous.

In a bit of water, a bit of salt will change its taste;
But this is not the case with the stream of the river Ganges.
Similarly, though our evil deeds may be very few,
They will be known in the context of all our virtuous roots.

Wild discursiveness and sinking in sluggish depression
Are states that will be harmful to dark and murky minds.
Sleepiness and doubt and yearning with desire,
These five obscurations are thieves of happiness.

However as for faith, pure effort, and mindfulness
The supreme dharmas of samadhi, and the five good prajñas
We should make an effort to manifest all of these.
Then there will be the highest powers and faculties.^[1]

In that way much that is to be transcended will be transcended, and good dharmas that are true and excellent will be established.
