Pure mind and the individual
The relationship of the two must be the hardest thing to express accurately in words. This difficulty has led to the great variety of attempts to express it better: "You have always had Buddha nature," "The Father and I are one," "That art thou," "The greatest medicine is the emptiness of everything," "Allah is the sustainer" and so on I have nothing to add to this millenia-old discussion except to say that perhaps I like the Zen approach the best: don't say anything about it at all. Just get the disciple to sit.
