here is the chronology of eastern teachings
Vedas:
The Jews of the East are called Brahmins and they are saying that to please blue gods during their orgies, the Jews, I mean the Brahmins , have to kill horses and cut very special woods in order to burn it and dance around the fire while chanting '''''''''magical & sacred''''''''''' sentences called '''mantras'''. Brahmins live off the royal families and have a comfy life, spending their day doing rituals mandated by the king, because the local Brahmin told him that the gods were somehow not pleased with the local king, until the king does what the brahmin recommends...
At this point karma, rebirth and meditation are not in the Vedas and do not matter. The only way to live the holy life is to be a born a Brahmin and do rituals around a fire and killing some animals once in a while. Brahmins rave about sacrifices.
Buddhism and so on
Then Buddhism, Jainism and some materialist gurus came along and said the Vedas and Brahmins are full of shit. Sainthood is not hereditary for instance. Buddhists introduce karma, aggregates are not self, and very precise meditation and their only goal is to ''end suffering''. They do not give a shit about politics. The Brahmins get super triggered and write the Upanishads as a counter attack.
The origin of the hindus and the buddhists isn't super clear. THe latest theory is that the brahmins were some indo-aryans and settled on the north west of India. The futur buddhists and jains were living at the Norf east of India. In the South there was some bums, whoever that was, and nobody cared. As the aryans moved towards the east, they encountered the futur jains and buddhists which later mogged the vedas big time.
