Acharya Prashant explains that a disciple's inability to surrender completely to a teacher stems from two primary factors: a lack of self-knowledge and a lack of knowledge regarding the teacher. The spiritual journey typically begins with self-knowledge, which is triggered by an experience of discomfort or a sense that something is missing despite worldly success. The teacher encourages this self-inquiry, but eventually, the student reaches a limit where their own perspective is no longer sufficient to progress. At this saturation point, the student must begin to know the teacher to gain a rejuvenated vision and see beyond their own limitations.
