Acharya Prashant explains J. Krishnamurti's concept that learning about oneself cannot be a gradual process. He distinguishes between external knowledge, such as understanding a petrol engine or learning a language, which requires time and mental effort, and internal realization. In the external world, complex systems are products of time and collective research, thus requiring time to master. However, the internal world is simple and consists only of honesty or dishonesty. Understanding oneself is a matter of immediate recognition rather than a prolonged study.
