In this belief, the soul is created in the image of God. Since God is Trinitarian, Mankind is "Nous", reason, both "logos" and "dianoia", and Spirit. The same is held true of the soul (or heart): it has "nous", word and spirit. To understand this better first an understanding of Saint Gregory Palamas's teaching that man is a representation of the trinitarian mystery should be addressed. This holds that God is not meant in the sense that the Trinity should be understood anthropomorphically, but man is to be understood in a triune way. Or, that the Trinitarian God is not to be interpreted from the point of view of individual man, but man is interpreted on the basis of the Trinitarian God. And this interpretation is revelatory not merely psychological and human. This means that it is only when a person is within the revelation, as all the saints lived, that he can grasp this understanding completely (see "theoria"). The second presupposition is that mankind has and is composed of "nous", word and spirit like the trinitarian mode of being. Man's "nous", word and spirit are not hypostases or individual existences or realities, but activities or energies of the soul - whereas in the case with God or the Persons of the Holy Trinity, each are indeed hypostases. So these three components of each individual man are 'inseparable from one another' but they do not have a personal character" when in speaking of the being or ontology that is mankind. The "nous" as the eye of the soul, which some Fathers also call the heart, is the centre of man and is where true (spiritual) knowledge is validated. This is seen as true knowledge which is "implanted in the "nous" as always co-existing with it".
