A while back, someone asked me about a theory that the lineage of seven buddhas was actually a Buddhist corollary to the true brahmin having seven generations of brahmin parents. I think it may have been @Vaddha, but there are probably others who will find my much delayed answer of interest, so I decided to post it as a little essay.
It turns out that EĀ 48.4 does provide us with some evidence that this may have been the case. It’s a early parallel of DĀ 1/DN 14 that consists of the first half of the fully developed Mahāvadāna Sūtra. When the end of the description of the seven buddhas is reached, it concludes with Ānanda asking questions. The main question is: Why did the Buddha recount only seven buddhas when there are countless buddhas in the past and future?
The Buddha answers:
The Tathāgata has taught the origins and incidentals of these seven buddhas because those origins and incidentals have their dependent arising. The buddhas of the past numbering like the sands of the Gaṅgā River also taught the origins and incidentals of seven buddhas. When Maitreya appears in the world, he will also describe the origins and incidentals of seven buddhas. If Arhat and Tathāgata Simha should arise, he will also describe the origins and incidentals of seven buddhas. When the Buddha Anuloma appears in the world, he will describe the origins and incidentals of seven buddhas. When the Buddha Pradyota arises in the world, he will describe the origins and incidentals of seven buddhas. When the Buddha Vimala appears in the world, he will describe the origins and incidentals of Kāśyapa. When the Buddha Ratnaprabha appears in the world, he will also describe the origins and incidentals of Śākyamuni.
“Simha, *Anuloma, *Pradyota,
Vimala, and *Ratnaprabha
Will all succeed Maitreya,
And they will achieve the Buddha path.
Maitreya will describe the Buddha Śikhin,
Simha will describe the Buddha Viśvabhu,
Anuloma will describe Krakucchandha,
Pradyota will describe Kanakamuni,
And Vimala will describe Kāśyapa,
All teaching their ancient circumstances.
When Ratnaprabha is completely awakened,
He will also describe my name.
The past Completely Awakened Ones
And those who will come in the future,
They will describe seven buddhas,
And their ancient origins and incidentals.”
Which we might visualize in this way:
Each buddha sees himself as the seventh of seven generations of buddhas. I would say that that this doesn’t have to directly relate to Brahmanism. Many cultures consider a certain number of ancestors to be important, and six generations in the past comes up in some Native American narratives, for instance. The seven generations of brahmins is an example of this way of recounting the past lineage of one’s people since the brahmins were originally a tribe rather than a class of people.
