For a perfect realisation, the whole being must be illumined; but for the beginning of a realisation, it is probably easier for a body that does not possess a very developed mind…. For us, well, who have reached the maximum possibility of the mind, it is through the maximum that we have gone beyond: it is only when the mind had realised its maximum that it abdicated. And this is quite all right for the integral realisation, but generally the body is too much used to obeying the mind, it is not supple enough to be transformed. And that is why my mind has been sent away…. But that is a method which others cannot be encouraged to follow. For out of ten nine would die.
