Acharya Prashant explains that confidence is often misunderstood as being derived solely from knowledge. While knowledge is useful for structured environments like examinations, it is inherently limited and inadequate for the complexities of life. He points out that the more one knows, the more one realizes the vastness of what remains unknown. True clarity comes from being empty of knowledge and recognizing its limitations. Confidence based on external information is fragile and easily shattered by the unpredictable nature of life, which does not follow a set syllabus or pattern.
