Bhagavat said: ‘What do you think, O Subhûti, is there anything (dharma) which the Tathâgata has adopted from the Tathâgata Dîpankara[1], the holy and fully enlightened?’ Subhûti said: ‘Not indeed, O Bhagavat; there is not anything which the Tathâgata has adopted from the Tathâgata Dîpankara, the holy and fully enlightened.’
Bhagavat said: ‘If, O Subhûti, a Bodhisattva should say: “I shall create numbers of worlds,” he would say what is untrue. And why? Because, O Subhûti, when the Tathâgata preached: Numbers of worlds, numbers of worlds indeed! they were preached by him as no-numbers. Therefore they are called numbers of worlds.
‘Therefore, O Subhûti, a noble-minded Bodhisattva should in this wise frame an independent mind, which is to be framed as a mind not believing in anything, not believing in form, not believing in sound, smell, taste, and anything that can be touched. Now, for instance, O Subhûti, a man might have a body and a large body, so that his size should be as large as the king of mountains, Sumeru. Do you think then, O Subhûti, that his selfhood (he himself) would be large?’ Subhûti said: ‘Yes, O Bhagavat, yes, O Sugata, his selfhood would be large. And why? Because, O Bhagavat, when the Tathâgata preached: “Selfhood, selfhood indeed!” it was preached by him as no-selfhood. Therefore it is called selfhood.’
