Acharya Prashant explains that the internal guru is always present and one is naturally surrendered to this inner truth from birth. He uses the metaphor of a fetus in the womb, whose head is naturally bowed, to illustrate that surrender is our original state. The problem arises when we begin to bow before worldly attractions, fears, and greed. He emphasizes that bowing before an external guru is a symbolic act of rebellion against the world, signaling that one's head will no longer bow to trivial worldly influences. True surrender to the internal guru means maintaining a straight spine and not being easily swayed by the market, advertisements, or emotions.
