Acharya Prashant explains that once a person has glimpsed the truth or taken even a single step toward it, they can never truly be destroyed. Shri Krishna reassures Arjun that even if a person becomes distracted or turns away from the path of truth, their progress is not lost. The speaker emphasizes that truth is so potent that even a small taste of it makes it impossible for a person to find satisfaction in falsehood or worldly distractions. Truth is described as a stubborn reality that, unlike lies, does not require constant repetition to exist; it remains valuable even when buried under the filth of the world.
