It’s Indigos in rotation bringing amethyst
The rotation of generations and the rise of indigos are gonna one day bring an end to this, (poverty, hate, crime, rape, etc). Only those who can see further than what the normal eye can, (i.e. the indigo child also known as STEEZ), have the ability to end what’s being presented, (the verse, or in a bigger context, the world’s struggle).
Amethyst is also a crystal used to open the third eye, (the pineal gland a.k.a the Ajna chakra).
It also sounds like he’s saying “into gold” when he says “indigo” which makes for great wordplay with alchemist. Gold is also one of the seven metals of alchemy.
