Son of Buddha wrote:
In the Pali Canon Anatman(Not-self) is viewed as suffering,what leads to suffering,and what belongs to Mara is Anatman.
In the Nirvana Sutra Anatman is viewed in the same way(i.e suffering and belonging to Mara).
And the True Self which is Buddha Nature is championed as the correct teaching/path.
Sorry, this sounds quite twisted. Realistion of Anatta dissolves suffering.
And i never heard of teachings given by Mara.
On topic: Buddhadasa Bikkhu (Theravada) said: if there is no teaching about emptyness (sunatta) somewhere in the sutra, the sutra is a fake. Maybe deformed by translation.
Sorry I was on my phone so I couldn't copy/paste/ and quote sources at that time, I can now.Here is the Info I was talking about in the Pali Canon
From Bhikkhu Bodhi Translation in book form found on PAGE 989 in the Samyutta Nikaya
in the Khandhavagga section
the Radhasamyutta chapter 2
under the 1. The First Mara Subchapter
(24 suttas where the Buddha teaches everything that belongs to Mara)
4 (2)-34 (12) Subject to Mara, tc.
... "Radha, you should abandon desire, you should abandon lust, you should abandon desire and lust, for whatever is subject to Mara '
..  ". for whatever is impermanent ... for whatever is of an impermanent nature for whatever is suffering ...
for whatever is of a painful nature for whatever is nonself ' .. for whatever is of a selfless nature
... for whatever is subject to destruction ... for whatever is subject to vanishing ... for what¬ever is subject to arising ... for whatever is subject to cessation. And what, Radha, is subject to cessation? Form is subject to ces¬sation. Feeling ... Perception ... Volitional formations ... Consciousness is subject to cessation. Seein thus ' .. He understands:
there is no more for this state of being.''
SN 22.46 Impermanent (2) pg 885
At Savatthi. "Bhikkhus, form is impermanent.... Feeling is impermanent.... Preception is impermanent.... Volitional formations are impermanent.... Consciousness is impermanent. What is Impermanent is suffering. What is suffering is nonself.
What is nonself should be seen as it really is with correct wisdom thus: This is not mine, this I am not, this is not my self."http://www.accesstoinsight.org/tipitaka ... .mend.html
Anatta-lakkhana Sutta: The Discourse on the Not-self Characteristic
Thus it was heard by me. At one time the Blessed One was living in the deer park of Isipatana near Benares. There, indeed, the Blessed One addressed the group of five monks."Form, O monks, is not-self; if form were self, then form would not lead to suffering
and it should obtain regarding form: 'May my form be thus, may my form not be thus'; and indeed, O monks, since form is not-self, therefore form leads to suffering
and it does not obtain regarding form: 'May my form be thus, may my form not be thus.'
Here is quotes from the Nirvana Sutra
"A person [might] say that all is non-eternal, meaning that even Nirvana is
non-eternal, and the same with
suffering, void, and non-self too.
That is why we say that such is non-grasping of the import of the sutras. One cannot depend upon such. O good man!
“Kasyapa said to the Buddha: "O World-Honoured One! Is there Self in the 25 existences or not?" The Buddha said: "O good man! "Self" means "Tathagatagarbha" [Buddha-Womb, Buddha-Embryo, Buddha-Nature]. Every being has Buddha-Nature. This is the Self. Such Self has, from the very beginning, been under cover of innumerable defilements.
