Acharya Prashant explains the internal fire of separation and longing for peace, which he describes as a 'fire without smoke' because it lacks external evidence or visible signs. This suffering is internal and can only be truly understood by someone experiencing the same state, often referred to as 'Ram-rog' or the sickness of longing for the Divine. He notes that the world often misinterprets this spiritual restlessness as madness or dissatisfaction with material success, offering worldly solutions like jobs or marriage that fail to address the soul's deeper thirst. This shared internal state is the true foundation of spiritual communities, where seekers find solace among those who understand their wordless pain.
