Acharya Prashant addresses a question about an Osho quote that calls seriousness a disease and playfulness the greatest health. The speaker begins by highlighting the apparent contradiction between Osho and J. Krishnamurti on the word 'seriousness'. While J. Krishnamurti was a great advocate for being 'very serious', Osho considered it a disease. The speaker clarifies that the difference lies in the connotation of the word used by each master. When J. Krishnamurti uses the word 'serious', he means to be sincere, to have a particular commitment towards the truth. It implies being undivided, earnest, honest, and dedicated in one's inquiry, not being heavy, loaded, or gloomy. It is about genuinely wanting to know, rather than just pretending. On the other hand, when Osho calls seriousness a disease, he is referring to a different mental attitude. For Osho, seriousness is the mind's tendency to become associated with something and then harbor great expectations or fears concerning it. This attitude arises from the conditioned mind, which feels that its essence is a temporary thing of this world. This leads to a fear of dissolution, causing one to clutch at external things for security or run away from them in fear. This clutching and running, born of fear and expectation, is the seriousness that Osho condemns as the greatest disease of the soul. It is based on the lie that one can gain the essential from something outside of oneself. Addressing the questioner's feeling of being stuck in a fear-based way of life, Acharya Prashant suggests that recognizing this is a great starting point, as there is nothing else to blame. If this one known way of living has brought no good, it should be given up. He advises dropping the old without trying to conceptualize or imagine what will come next, because the new cannot be predetermined by the old mind. Using the analogy of a clot over a wound, he explains that the clot falls away only when new skin has already formed underneath. Similarly, the new has already arrived, which is what empowers one to drop the old and rotten. The going away of the old does not require one to first know what will come next; what is to come has already arrived, enabling the old to depart.
