I read in a translation of Vimalakirti Sutra by Robert Thurman at http://www2.kenyon.edu/Depts/Religion/F ... akirti.htm:
And later:The Buddha said, "Noble sons, a buddha-field of bodhisattvas is a field of living beings. Why so? A bodhisattva embraces a buddha-field to the same extent that he causes the development of living beings. He embraces a buddha-field to the same extent that living beings become disciplined. He embraces a buddha-field to the same extent that, through entrance into a buddha-field, living beings are introduced to the buddha-gnosis. He embraces a buddha-field to the same extent that, through entrance into that buddha-field, living beings increase their holy spiritual faculties. Why so? Noble son, a buddha-field of bodhisattvas springs from the aims of living beings.
"For example, Ratnakara, should one wish to build in empty space, one might go ahead in spite of the fact that it is not possible to build or to adorn anything in empty space. In just the same way, should a bodhisattva, who knows full well that all things are like empty space, wish to build a buddha-field in order to develop living beings, he might go ahead, in spite of the fact that it is not possible to build or to adorn a buddha-field in empty space.
"Yet, Ratnakara, a bodhisattva's buddha-field is a field of positive thought. When he attains enlightenment, living beings free of hypocrisy and deceit will be born in his buddha-field.
I am still unsure of what is meant. Especially the sentence"The purity of his buddha-field reflects the purity of living beings; the purity of the living beings reflects the purity of his gnosis; the purity of his gnosis reflects the purity of his doctrine; the purity of his doctrine reflects the purity of his transcendental practice; and the purity of his transcendental practice reflects the purity of his own mind."
Of what living beings I wonder?The purity of his buddha-field reflects the purity of living beings
It means the living beings that are in the buddha field? Is it meant like that you train your mind a certain way you will perceive your reality in that way? Like if I train myself to mostly see things in a positive light, like I read in a book by Tulku Thondup "see the positive in every situation", that then you will mostly perceive everything around you as pure and good? Thus all the living beings you encounter will seem (be?) like that in your reality?
