Acharya Prashant explains that the core and gloss are inseparable entities, much like the mind and body. The core represents the essence and intelligence from which all actions arise, while the gloss is the perceivable manifestation of that core through one's actions, appearance, and voice. He clarifies that when the core becomes apparent to the senses, it is called gloss, and when gloss is traced back to its roots, it is the core. The speaker distinguishes these natural expressions from the 'mask,' which refers to artificiality, fake personalities, and deception. Unlike the mask, which is cunning and artificial, true gloss is the healthy and natural expression of an innocent mind. Acharya Prashant emphasizes that one cannot and should not attempt to remove the gloss, as it is the natural brightness resulting from internal health and clarity. Just as a healthy tree has shining leaves and a real flower possesses a natural scent, a person with internal soundness will naturally exhibit beauty in every word and action. He argues that the need for artificial makeup or masks only arises when the internal state, or the core, is unhealthy or diseased. Therefore, the focus should remain on taking care of the core, as it will inevitably provide a beautiful and sufficient gloss on its own.
