Paroksa and Aparoksa
Knowledge is twofold: paroksa - indirect and intellectual - and aparoksa - direct and intuitive.
The former is knowledge by contact, via a medium - e.g., scripture, guru.
The latter is knowledge by identity - it is immediate knowledge, without a medium.
It arises from direct experience.
Such knowledge is real knowledge.
It puts an end to all doubt and uncertainty.

Advice
