is there any philosophical arguments or reasons for this doctrine besides scriptural appeal in Tiantai?Coëmgenu wrote:This is off-topic, but the Mahāyāna doctrine comes from the Lotus Sutra, through interpretation by Tiantai, and the Mahāyānabrahmajālasūtra:There are multiple mindstreams, but one Buddhahood, in the Lotus tradition at least.Now, I, Vairocana Buddha, am sitting atop a lotus pedestal; on a thousand flowers surrounding me are a thousand Sakyamuni Buddhas. Each flower supports a hundred million worlds; in each world a Sakyamuni Buddha appears. All are seated beneath a Bodhi-tree, all simultaneously attain Buddhahood. All these innumerable Buddhas have Vairocana as their original body.
Do mindstreams melt into Buddhahood at elightenment like souls melt into Brahman in Vedanta? I know the metaphor of the waves and the ocean is a common one in east asian Buddhism.
