Another enumeration is that imputed form, that is, the dependent nature,
permanently and constantly lacks the imaginary nature, that is, the
two natures of subject and object. [273b] [This lack or] emptiness is the
form of reality, the consummate nature. This30 statement, emptiness is
form, indicates that both the dependent and the consummate are identical
because emptiness, the consummate nature, and form, the dependent
nature, are determined to be identical. Therefore, it is just said that emptiness
is form.
Having stated their identity from a positive standpoint, it is also stated
from a negative standpoint. Emptiness is not other than form refutes
their difference. Because it is thoroughly established as unchanging and
unmistaken, it is consummate. Because it is not made by potencies upon
the conjunction of causes and conditions, it is unconditioned. Duality,
which is other than that, is not established. Because its continuum is not
severed, it is permanent. It is the dharmakaya of the Mahamuni [Buddha];
it exists ultimately.31 It alone is the ultimate truth; thus it is said to
be nirvana, having the character of nonobscuration. There is the famous
statement that if this were not so,32 then all undertakings become
meaningless.
How can those who assert that the nature of the dharmakaya as it was
set forth33 [above] understand it to exist ultimately,34 when it is [in fact]
dependent?
