Bodhisattva Bhumi; bodhisattva-bhumi, Bodhisattva Stages by Asanga [RY]
In The Light of Wisdom, vol. I, under the heading of the perfection of Discipline on pg. 123, it states that, although the Bodhisattva Bhumi has taught eleven types (of trainings), such as helping in meaningful actions and so forth, in short there are generally three trainings:
For the first, carefully observe the general seven types of Individual Liberation (so thar ris bdun) and the specific trainings of the bodhisattva precepts which stem from the traditions of the Two Chariots (shing rta gnyis) and thus henceforth to constrain yourself from committing the misdeeds of your three doors by interrupting negative conduct.
For the second, practice as much as you can the conditioned virtues which are not embraced by discriminating knowledge and which are chiefly connected with the actions of body and speech, as well as the unconditioned virtues which are embraced by discriminating knowledge and are cheifly connected with the samadhi of mind.
For the third, to simply motivate yourself with the superior intention to carry out all your deeds, whatever you do with your three doors, exclusively for the sake of other sentient beings. Then actually engage as much as you can in activities which are of benefit to others.
