When, with the creative energy of pure presence, which is an energetic response to what is present, one concretises these hues, one goes astray because one does not understand them as both a lucid presence and as nothing. By appropriating the presence of these five hues into one's existence as a thing, one goes astray into a conceptualised essence. By appropriating the presence of these five spontaneous hues, the five external phases arise, as in the view of the heretics in which they are taken as eternal.

-- Padmasambhava, Guru Rinpoche
