Emanuael Swedenborg wrote : 'Und daß sie bei Beschreibung des Ursprungs der Wissenschaften aus dem Verstand, ein geflügeltes Pferde darstellten, das mit dem Huf eine Quelle aufstieß, an der neun Jungfrauen waren, welche die Wissenschaften bezeichnen; denn aus den alten Kirchen war ihnen bekannt, daß durch das Pferd das Verständnis bezeichnet werde, durch Flügel geistig Wahres, durch den Huf Wissenschaftliches aus dem Verständnis, und durch die Quelle die Lehre, aus der die Wissenschaften stammen. Durch das Trojanische Pferd wurde nichts anderes bezeichnet, als ein ihrem Verstand entstammender Kunstgriff, die Mauern zu zerstören. Wenn heutzutage der Verstand in der von jenen Alten überkommenen Weise geschildert wird, pflegt er zwar durch ein fliegendes Pferd oder den Pegasus dargestellt zu werden, die Lehre durch eine Quelle, und die Wissenschaften durch Jungfrauen; aber kaum jemand weiß, daß das Pferd im mystischen Sinn das Verständnis bezeichnet, 'Über das weiße Pferd in der Offenbarung.'

In the Mahabharata the horse sacrifice was of great importance. It was carried out only by and to the exaltation of kings. 100 such Aśwamedha horse horses should make a mortal king stronger than Indra. A horse of a particular color was selected and then released for free wandering for 1 year. When the horse entered a foreign country, the ruler had to subdue or fight. When the liberator of the horse succeeded in subduing the lands, he returned in triumph with the defeated Rajas in his retinue. Otherwise, he was insulted and his claims mocked. After the successful return, a great festival took place, at which the horse was killed, either real or figuratively. Yudhishthira's big Aśwamedha horse-sacrifice set off a wild black horse from Hastinapur (City of the Elephants), which the Kurus had to follow everywhere.
The Brhadaranyka - Upanishad begins with a passage that strengthens the cosmic symbolism of the aswa.Chapter 1 The world as a sacrificial horse begins with a correspondence between the physiology of the horse and the external world order, and the mysticism of the correlation can not be wrong:
“ Aum, the dawn, truly, is the head of the sacrificial horse, the sun is the eye, the wind the breath, the open mouth the Vaishvanara fire. The year is the body of the sacrificial horse, the sky is the back, the atmosphere is the belly, the earth the hoof, the quarter the sides, the intermediate quarters the ribs, the seasons the limbs, the months and the half months the joints, days and nights the feet, the stars the bones, the clouds the flesh. The food in the stomach is the sand, the rivers are the blood vessels, the liver and the lungs are the mountains, the herbs and trees are the hairs.
The rising (sun) is the forefront, the sunset is the back part, when it yawns then it brightens, when it shakes it thunders, when it urinates then it rains. The voice is indeed his voice.
Chapter 2: Truly the day came after the horse when the (golden) vessel, called Mahiman (greatness), before the horse is placed. Its place is in the eastern sea. The night came after the horse was placed as a ship, called Mahiman, behind the horse.
Its place is in the western sea. Certainly, these two vessels (or generations) emerged to be on each side of the horse. As a racehorse it carried the Devas, as a stallion the Gandharvas, as runners the Asuras, as a horse the humans. The sea is his family, the sea is his birthplace...

Black horses represent low-minded thinking with its false ideas and erroneous human concepts. The broodmares as we encounter them in this first task point to the feminine aspect of thinking as it creates ideas, theories, and concepts.
The inclination of thinking to create thought forms is symbolized here, how it dresses the received ideas into forms, which are released to the world, and when they flow out of the lower thinking, they are devastating and destructive, but building and redeeming when they come from the soul(Alice bailey : The labours of hercules, Pg. 34)
