The perfection of ethical discipline
The Immaculate (Vimala)
The Bodhisattva posses the qualities of most prefect morality and therefore, even when dreaming, he (she) renounces any defilement which would violate his (her) moral behaviour. From purification of physical, verbal, and mental acts he (she) consolidates the ten paths of pure conduct.
With his (her) entry into [the second stage] this tenfold path of virtue is brought to extreme purity. Like the autumn moon he (she) is always pure, and through following these [then paths] he (she) is made beautiful with the radiant light of peace.
If, however, he (she) were to view [any aspect of] this pure morality as instrinsically existent, then it would no longer be "pure" morality. Therefore he (she) remains totally aloof from the influence of dualistic ideas concerning any of the three supports.
For a person whose morality is deficient, the goods resulting from charity may appear even in a bad migration; but when the bulk of them has been spent along with any other which the produced, there will be no more such goods in the future.
When [a person] lives with independence and under agreeable circumstances and still neglects to take firm hold of himself (herself), then he (she) will tumble into the abyss and be delivered over to the power of others; and once this has happened, who will lift him (her) up?
Because of this, the Conqueror gave instructions in moral conduct just after teaching about generosity. [All] good qualities thrive in the soil of morality, and the enjoyments of its fruits never ceases.
For common men (women), for [sravakas] born from the words [of a buddha], for the individual [awakening] of pratyekabuddhas, and for the sons (& daughters) of the conquerors, the essential cause of temporary happiness as well as incomparable bliss is none other than morality.
Just as in the case of the ocean with respect to a corpse, or as it is with prosperity in the face of misfortune - so a mighty one governed by the force of morality is unwilling to live with any transgression.
When there is any [belief in an] objective support associated with these three - he (she) who abstains, the act of abstention, and the object of that act - then such morality is called a mundane perfection; but that which is empty of attachment to the three of them is referred to as a supramundane perfection.
Issuing forth from that moon which is the son (daughter) of the conquerors, this immaculate [stage] is not worldly, and yet it is the glory of the world. Stainless and pure as light from the autumn moon, it dispels the burning heat that torments the heart of every living being.
