Acharya Prashant explains that meditation is not a limited one-hour daily practice but a continuous, life-long state of being. He critiques the popular notion of 'clean' meditation, where individuals spend their day in conflict and ego-driven actions only to seek an hour of artificial peace. Real meditation is described as a 'dirty' and difficult process because it requires an individual to confront the reality of their daily life, actions, and ego without any decoration or self-deception. It is like showing a mirror to oneself, which can be hurtful and scary as it involves acknowledging the 'stinking ego' rather than pretending to be the supreme truth.
