According to Spiritism and also some Dharmic religions, our souls/consciousness can reincarnate unlimited times until we attain moral and intellectual improvement. We will them gain a certain vibration (that can be high or low) or a karmic balance.
After we die accordingly with our karmic balance we choose our next life as humans (or according to Hinduism maybe another species), we literally plan our next life including how we die, in order to keep learning and improving.
The thing is when we reincarnate our soul forgets what we came to learn and because of that life will throw challenges at you to direct you into the right path.
But what if Astrology (and other occult sciences) can give us a hand and a heads up on what to start?
