Acharya Prashant explains that the Guru is not a personality but the very point of resolution where all problems cease. He describes human existence as a collection of problems and questions, from the physical body to the mind, all seeking a solution. The Guru represents that ultimate solution or truth that our entire being is restless to reach. This journey is not a physical one but a mental and spiritual progression toward the final point of peace. He emphasizes that the Guru is essentially Truth itself, which may or may not manifest through a person.
