Acharya Prashant explains that the primary purpose of spirituality is to derive actual benefit rather than just engaging in intellectual curiosity. He describes the role of a Guru as one who works 'under the radar,' often using words and stories as a distraction to keep the seeker's mind from wandering, while the real transformation happens silently and beyond the reach of the senses. He uses the analogy of a doctor distracting a child with a toy to administer a necessary injection, emphasizing that the true value lies in the silent transmission that occurs beneath the surface of conversation. Words are merely the 'sugar coating' for the medicine; if words alone could bring liberation, everyone who has read the scriptures would already be enlightened.
