Perceiving that the triple existence is by reason of the habit-energy of erroneous discrimination and false reasoning that has been going on since beginningless time, and also thinking of the state of Buddhahood which is imageless and unborn, [the Bodhisattva] will become thoroughly conversant with the noble truth of self-realisation, will become a perfect master of his own mind, will conduct himself without effort, will be like a gem reflecting a variety of colours, will be able to assume the body of transformation, will be able to enter into the subtle minds of all beings, and, because of his firm belief in the truth of Mind-only, will, by gradually ascending the stages, become established in Buddhahood. Therefore, Mahāmati, let the Bodhisattva-Mahāsattva be well disciplined in self-realisation.
First, here is a good all-around text to get around some of the Sanskrit (I belive) terminology. Tibetan, I believe, but as long as I'm going through this, I'd prefer to understand it. It's why I started doing this.
Much of IX is about the fact that the various forms of conciousness "grow out of their attachment to the discrimination which is applied to the projections of Mind itself." But, regarding the Bodhisattva...
Only those who, understanding fully all the aspects of the different stages of Bodhisattvahood by the aid of their transcendental knowledge, acquiring a definite cognition as regards the meaning of the separate propositions, planting roots of goodness in the Buddha-lands that know no limits, and keeping themselves away from the discriminations and false reasonings that arise from recognising an external world which is of Mind itself, would retire into a secluded abode in the forest and devote themselves to the practice of the spiritual discipline, either high, or low, or middling, only those are capable of obtaining an insight into the flowing of Mind itself in a world of discrimination, of being baptised by the Buddhas living in the lands without limits, and of realising the self-control, powers, psychic faculties, and Samādhis. Surrounded by good friends and the Buddhas, Mahāmati, they are capable of knowing the Citta, Manas [sense of self], Manovijñāna[i. e., the thinking function of consciousness], which are the discriminating agents of an external world whose self-nature is of Mind itself; they are capable of crossing the ocean of birth and death which arises by reason of deed, desire, and ignorance. For this reason, Mahāmati, the Yogins ought to exercise themselves in the discipline which has been given them by their good friends and the Buddhas.
