In the above image, we see a paining of Surya, the sun God, from the 19th Century. Surya is seated on his chariot led by a horse with seven heads. He is surrounded by attendants and the multitudes praise him. It is said that Surya is the eye of the cosmos. 
In images of the cosmic person, Surya is one the eyes, contrasting with the moon in the other eye, representing the solar and lunar aspects of both the cosmos and psychic life.
In Symbols of Transformation, Carl Jung contemplates the nature of the sun God as a representation of creative power. This force is both cosmic, as represented by the image of the sun God and psychical as represented by the concept of libido. Jung says:
“The sun is perfectly suited to represent the visible God of this world, i.e., the creative power of our own soul, which we call libido, and whose nature it is to bring forth the useful and to bring forth the useful and the harmful, the good and the bad” (CW 5, para. 176).
The sun is an image of ‘the visible God’ and of ‘the creative power of the soul.’ This creative power is both cosmic energy and psychic energy. As an “astromythological” image, Surya tells the story of “the father-god from whom all living things draw life; he is the fructifier and creator, the source of energy for our world.”
The mythology of the sun God is complex. On the one hand the sun God is an image of wholeness. Jung tells us that the sun God transcended the split we see in the “moral division into a Heavenly Father and his counterpart the devil” (ibid).
On the other hand, the sun God reflects powerful psycho-dynamics inherent in the instincts. The instincts are both creative and destructive, libidinal and aggressive. The same psychic force that leads us to fall in love, may also lead us into destructive acts.
Instincts are by their very nature an innate and natural pattern of behavior in response to stimuli. These psychic forces are both creative and destructive. Freud called these psychic forces the life and death drives. Jung does not see a split in the drive, as Freud did. Instead, he sees these psychic force as emerging from one source, like the sun. Yet, this one instinctual source is capable of producing both creativity and destructive acts. Borrowing from astromythological motifs of the sun, Jung says:
“The sun is not only beneficial, but also destructive; hence the zodiacal sign for August heat is the ravaging lion which Samson slew in order to rid the parched earth of its torment. Yet it is in the nature of the sun to scorch, and its scorching power seems natural to man. It shines equally on the just and the unjust, and allows useful creatures to flourish as well as the harmful” (ibid).
The sun not only offers a life engendering potential, but also that of destruction. The sun is both the source of life and of tormenting, burning heat. The image of the power of the sun God is perfectly suited to express both the wholeness of libido, as well as the creative and destructive poles of psychic life.
