Astrology is a science. But in some way, it is a lost science.
The complete knowledge is not available, so whatever knowledge they have is 70 to 80 percent. They are able to predict something about it.
But there is one clause astrologers always give. There is a bigger power hiding behind, a higher power, which can overrule all of this. Because that superior power, that super power is independent and that is the Divinity, the Divine grace. The Divine grace can change anything at any time.
