Learning by self-experience is not absolute or it cannot be guaranteed that whatever your are learning by self-experience is 100% true.
As this mode of learning has four defects namely:
- Incorrect observation (for e.g. mirage in a desert or on road during a hot sunny day)
- Inability to learn 100%
- Doubt about any facts
- Limited ability to experience (for e.g., we can hear a sound up to a certain volume, we can see up to a certain distance, etc.).
