It's in the definition of the word, occult.
The majority of people aren't equipped to handle occult teachings and would inevitably corrupt it into lesser forms, plus there are stigmas around anything deviating from the norm in every society. If we take the Buddha as an example, the teachings he gave publically in the suttas/sutras are much more general and failproof. That path will lead to enlightenment, surely, but at a slower rate. Whatever was transmitted directly to individual disciples, or written down in the (secretly kept) tantras, are the occult teachings of Buddhism.

That already happened with the worker caste. Communism, Nazism, and Masonry all come from this tard.
