Son of Buddha wrote:
I suppose if Enlightenment is one then all Buddhas are perfectly one with one Full Enlightenment,unless Enlightenment is different for all Buddhas.
thats like saying a brown cow and a white cow arent both cows, because theyre different cows.
(the enlightened Shakyamuni and the enlightened Maitreya arent both enlightened, because theyre different enlightenments)
shentong isnt monism because it knows how to resolve this question using imputation, whereas nonbuddhists systems do not
your analogy is based on the physical where as Enlightenment is on the mind/mental.
here lets replace cow with human in this analogy
you may have two humans one black one white,but would you say they have the same mind?
no each person has a seperate individual personality,one perosn has nore wisdom than the other,one person likes night the other day,when it comes to views both disagree with each other concering different topics.
now does the Buddhas/Enlightenement have different personalities?does Amitabha Buddha have more pristine wisdom than Shakyamuni Buddha? or is the same pristine wisdom?
does Amitabha Buddha have different Views on topics or Dharma than Shakyamuni Buddha,which emans they will disagree with one anouther,or do the share the same exact views in said topic.
is Amitabha Buddhas morality better Than Shakyamuni Buddhas morality or is it the same?
Is Amitabha Buddhas enlightenment better than Shakyamuni Buddhas enlightenement?
or is it the same Enlightenment?
you can read Lankavatara sutra Chapter 3 LX on this matter.
(141) At that time again, Mahāmati the Bodhisattva-Mahāsattva said this to the Blessed One: According to what deeper sense2 did you make this announcement before the congregation, that "I am all the Buddhas of the past," and that "I have gone through many a birth in varieties of forms, being thus at times the king Māndhātṛi, Elephant, Parrot, Indra, Vyāsa, Sunetra, and other beings in my one hundred thousand births?"
Said the Blessed One: There are, according to the deeper sense, four kinds of sameness distinguished, Mahāmati, and the Tathagatas, Arhats, Fully-Enlightened Ones make this assertion: I was thus at that time the Buddha Krakucchanda, Kanakamuni, and Kāśyapa. What are the four kinds of sameness which are distinguished according to the deeper sense? They are: (1) sameness of letters, (2) sameness of words, (3) sameness of teachings, and (4) sameness of the body. According to this fourfold sameness in the deeper sense, the Tathagatas, Arhats, Fully-Enlightened Ones make the announcement before the congregation.
2 Saṁdhāya. There is no reference to this in Wei and Sung. The term has a special sense here and elsewhere in the Laṅkāvatāra.
Now, Mahāmati, what is the sameness of letters? It is that my name is [spelt] B-u-d-d-h-a, and these letters are also used for other Buddhas and Blessed Ones; Mahāmati, these letters in their nature are not to be distinguished one from another; therefore, Mahāmati, there is the sameness of letters.
Now, Mahāmati, what is the sameness of words with regard to the Tathagatas, Arhats, and (142) Fully-Enlightened Ones? It is that sixty-four sounds of the Brahman language are distinguished by me, and these identical sixty-four sounds of the Brahman language are also uttered by the Tathagatas, Arhats, and Fully-Enlightened Ones, and their Kalaviṅka-like notes are the same with all of us, as we are indistinguishable in this respect.
Now, Mahāmati, what is the sameness of the body? It is that I and other Tathagatas, Arhats, Fully-Enlightened Ones are the same as regards our Dharmakāya and the [thirty-two] signs and the [eighty] minor excellencies of bodily perfection—no distinction existing among us, except that the Tathagatas manifest varieties of forms according to the different dispositions of beings, who are to be disciplined by varieties of means.
Now, Mahāmati, what is the sameness of the teaching? It is that I as well as they [other Tathagatas] are all conversant with the teachings belonging to the thirty-seven branches of enlightenment. According to the deeper sense which is concerned with this fourfold sameness, the Tathagatas, Arhats, Fully-Enlightened Ones make their announcement before the congregation. So it is said:
6. "I am Kāśyapa, Krakucchanda, and Kanakamuni"; this I preach who come out of the sameness for the sake of the sons of the Buddha.
now go to LXI
"all Buddhas and myself/in nothing do we differ.
For instance, Mahāmati, Indra is [sometimes known as] Śakra, [sometimes? as] Purandara; hand is hasta, kara, paṇi; the body is tanu, deha, śarīra; the earth is pṛithivī, bhūmi, vasuṁdhara; the sky is kha, ākāśa, gagana; all these objects each in its way are designated with many names, synonymously used and discriminated; but on account of these different names different objects are not to be imagined, nor are they without their self-nature. The same, Mahāmati, can be said of myself, for I come within the range of hearing of ignorant people, in this world of patience, under many names, amounting to a hundred thousand times three asaṁkhyeyas, and they address me by these names not knowing that they are all other names of the Tathagata.
