After asking the Eternal Spirit, I think the quote means we do not have enough aspiration for ending suffering.
This is because we have not seen clearly enough for ourselves what suffering is.
It is like we have been sold an advertised dream of awakening rather than sought for ourselves a medicine for our self-diagnosed problems.
To find the Eternal Spirit, we must dream of the Eternal Spirit, which is that place of clarity & stillness within us.
To dream of the Eternal Spirit is the best of dreams. The Eternal Spirit is the purist of cleansing medicines.
