From imagination to skillful means

Further, Mahamati, the Bodhisattvas who are thoroughly acquainted with the nature of the Citta, Manas, and ManoVijnana, of the five Dharmas, of the [three] Svabhavas, and of the twofold Egolessness, will assume various personalities for the sake of benefitting others, just like the imagination that evolves from the seat of the relativity knowledge, and again, like the mysterious gem that reflects varieties of colours.

Going over to all the Buddha-lands and assemblages, the Bodhisattvas will listen to the Buddhas, discourse on the nature of all things which are like a vision, a dream, an illusion, a reflection, and the lunar vision in water, and which have nothing to do with birth-and-death, eternality, and extinction; the Bodhisattvas, thus facing the Tathagatas, will listen to their discourses on the truth that does not belong to the Sravaka- and Pratyekabuddha-vehicle.

They will then attain a hundred thousand Samadhis, indeed, a hundred thousand niyutas of kotis of Samadhis, and by means of these Samadhis they will go around from one country to another; they will do homage to the Buddhas, be born in all the celestial mansions, where they will discourse on the Triple Treasure, manifesting Buddha-bodies; and, surrounded by Sravakas and Bodhisattvas, they will, in order to free them from the alternatives of being and non-being, instruct them to understand thoroughly what is meant by an objective world which is nothing but Mind itself and in which there are no realities. ~ The Lankavatara Sutra
