Acharya Prashant explains that Swami Vivekananda was not an imitator; rather, his transformation occurred because his Guru, Shri Ramakrishna, completely dissolved the personality of 'Narendra'. He emphasizes that a Guru's primary role is to cleanse the disciple of their ego and the things they value most. The true self, or the 'sky', is always present and eternal, whereas the personality and its attachments are like 'clouds' or 'smoke' that are temporary occurrences. To experience the clear sky of reality, one must be willing to sacrifice these clouds of ego. Acharya Prashant asserts that spirituality is essentially the art of sacrifice. He observes that those who receive spiritual teachings for free or without effort often fail to benefit because they have not paid a price. Without paying a price—whether through physical effort, discomfort, or giving up something valuable—the ego remains intact. He reflects on his own experience, noting that his attempts to distribute knowledge for free were often unsuccessful because the lack of sacrifice prevented the recipients from becoming true seekers. He concludes that a Guru must recognize the specific capacity and nature of each disciple to guide them effectively, as different individuals require different approaches to overcome their attachments.
