Acharya Prashant explains that bliss is the state of remaining undisturbed and steady amidst all experiences, whether of pleasure or pain, while walking the path of truth. He clarifies that merely enduring hardships is not bliss; rather, it is the ability to remain unaffected by external sensations because one is deeply immersed in something far more significant and attractive within. He uses the analogy of a person watching a captivating play who does not notice mosquito bites, or a person in Kashmir carrying a 'Kangri' (a portable heater) under their clothes to withstand the freezing cold. This internal warmth or connection to truth allows a person to navigate the world's adversities without being shaken.
