But there is no reason to believe that the ascendant was of interest as such, as it is not expressly mentioned.
The other great epic of India, the Rāmāyaṇa, does not contain any clue to astrology as we know it either, at least not in its original form.
It only appears in versions of the northern recension, and the critical edition of the epic only quotes it in the critical apparatus.
Passages in the Purāṇas that mention zodiac signs also have to be dated to the Hellenistic epoch.
Thus in their opinion, culture was not developed in terms of a progressive upward development, as Westerners believe, but was established at the beginning of time by divine beings in highest perfection and since then has only deteriorated.
For this reason, Hindu traditionalists tend to interpret western notions of the history of culture, which assumes that the ancients were more primitive than we are, as an insult or their greatest saints.
While Indian astrology may be “Vedic” in that it is part of today's Vedic tradition, it is in fact a lot younger than the Vedas and has many elements which were not developed in India but in Mesopotamia, Egypt, and Greece.
The Vedas themselves, the core corpus of sacred writings of Hinduism (śrutiḥ), are mainly interested in the position of the moon in the 27 or 28 lunar mansions, as well as in the lunar phases, eclipses, the solstices, and the equinoxes.
The traditional expression is simply jyotiṣam, i.e. The term “Vedic astrology” appeared only in recent decades, with the aforementioned boom of Hindu astrology in the West.
The term “Vedic” is often used to express the idea that this astrology is a sacred science, which was revealed by the Rishis, the founders of Vedic wisdom, more than 5000 years ago and was handed down from generation to generation without any changes until the present day.
Incidentally, it should become obvious from my explanations that Vedic religion as it has been handed down in Vedic literature, has nothing to do with the so-called "Vedic astrology" as practised today.
