[Daruhuw]

The sources are Nagarjuna and the prajnaparamita texts.

I thought we were into Thich Nhat Hanh's "The Heart of the Teachings of the Buddha". There he insists in a kind of "storage" where seeds of consciousness are given... trying to depict the fifth Khandha as the stuff that goes from one life to another.

I have to confess that I am neither into Nagarjuna nor the Prajnaparamita suttas. They are not about the historical Buddha teachings but even that, we all know, that Mahayana become a religion and in its becoming into that, this traditon managed the not self doctrine so to set something that [needs to] endures so to bring some sense to life after death (the rebirth of them).
