This is an under appreciated sutra nowadays. A sample from chapter five on Non-attachment:
The Buddha said to Bhadrapala: "How should this meditation for
bodhisattvas be undertaken? Just as I, the Buddha, am now preaching
sutras in your presence, bodhisattvas should think that the
Buddhas are all standing before them; they should call to mind in
full the Buddhas, who are upright, whom everyone wants to see.
They should think of each and every mark, recalling that no one
can see the tops of the Buddhas' heads. They should think of all
this in full, and they will see the Buddhas.
They should think:
I myself will also be like this, I will also acquire such bodily marks
as these, and will also attain such morality and meditation as
these.' They should think: 'Will I attain this through the mind or
will I attain it through my body?' They should think again: 'The
Buddha did not attain it by means of the mind, nor did he attain it
by means of the body. Buddhahood is not attained by means of the
mind, nor is it attained by means of form. Why? As for mind, the Buddha
has no mind; as for form, the Buddha has no form. It is
not by means of this mind and form that one attains supreme and
perfect awakening. Why? The Buddha's form has come to an end,
the Buddha's feelings, conceptions, birth-and-death, and consciousness
have come to an end, and what the Buddha preaches has
come to an end, which is not perceived or known by fools, but is
understood by the wise.
