Acharya Prashant explains the fundamental difference between the 'Adhir' (impatient or worldly person) and the 'Sadhu' (saintly person) using the metaphors of glass, lead, and gold. He states that worldly people are like glass or lead; they break easily under the heat of trials and tribulations because they lack patience and depth. In contrast, a Sadhu is like gold; the same heat and trials that break others only serve to make the Sadhu shine brighter and become more refined. He emphasizes that one's experience of life depends not on external circumstances, but on one's internal orientation, much like how the same wind can sink one ship but provide direction to another depending on how the sails are set. He defines a 'Durjan' (wicked or ignorant person) as someone who mistakes the transient for the eternal, such as mistaking the morning star for the sun. Such a person builds their life on the 'quicksand' of the world, attaching themselves to people, images, and material things that are destined to perish. When these attachments inevitably break, the person suffers immensely. Acharya Prashant points out that every worldly image is bound to shatter, and those who anchor their identity in them are preparing themselves for inevitable pain. The worldly person's world is fragile because it is built on things that are 'airy' and temporary. Conversely, the Sadhu is one who has established their home in the 'Nitya' (the Eternal), where the question of coming and going does not arise. Acharya Prashant compares the Sadhu to the sky or the ocean; just as missiles cannot destroy the sky and sticks cannot break the ocean, the world cannot touch or diminish the Sadhu's true essence. Even if a Sadhu's physical belongings are taken or their body is harmed, they remain unbroken and joyful. He concludes that while the worldly person is destined to break, the Sadhu is like a self-righting toy—no matter how many times circumstances knock them down, they immediately stand back up because they are rooted in that which is indestructible.
