Acharya Prashant explains that Zen is not something to be understood through definitions or roundabout questions, but rather something that happens when one directly engages with a Zen koan. He emphasizes that koans are not meant to provide comfort or easy answers; instead, they are designed to deliver jolts that break the seeker out of their usual patterns of thinking. To truly approach Zen, one must be prepared for uncertainty, disillusionment, and the loss of all mental supports. He describes Zen as a state of absolute vacancy where there are no concepts, teachings, or methods, because the destination is immediate and always in the present moment. Zen practice, therefore, involves approaching things without the need for definitions and being brave enough to face the assault that such a practice launches on the ego. Regarding the concept of self-realization and the body, Acharya Prashant clarifies that realization is not a target to be achieved but a process of 'unrealizing' or stripping away the rubbish of concepts and dirt picked up through time. He asserts that a realized person has no essential connection to the body, viewing it as a physical instrument of nature that operates on its own. Using the metaphor of the sky and a ripening fruit, he explains that while the fruit exists within the sky, the sky remains unaffected by the fruit's growth or eventual fall. Similarly, a realized being is a witness who neither clings to the body nor seeks to destroy it, remaining indifferent to its birth or death. He concludes that the obsession with the physical body or 'the fruit' often prevents people from appreciating the 'sky' of essential nature.
