Both the natal chart - can reveal hidden talents based on planet placement in houses, aspects to other planets, etc in which I pick-up on intuitively.

Besides the natal chart there is the progressed and many other types of charts in western (tropical) and eastern or Jyotish astrology.

The other higher self chart is not based on the soul. It reveals the Higher Self. It based on the use of harmonic charts often used in other ways by Jyotish (Hindu) Astrologers. Very few if any other astrologers except myself and a former teacher of mine use harmonic charts to map first layers of the the higher self.
