How does Chapter 16 emphasize the importance of faith and humility when approaching a Guru?

Chapter 16 of the Sai Satcharitra strongly underscores the necessity of faith and humility. It states that if a leaf or flower is offered with faith, the Sadguru accepts it with great love, but if the same offering is made with pride, He will turn His face away immediately. The chapter warns that even a slight neglect in service or the use of 'cleverness' can lead a seeker into trouble. Therefore, it advises that a disciple should simply surrender completely to the Sadguru, as 'Firm faith at His feet is necessary.' Serving Him with this sincere faith is presented as the path to attaining union with Brahman.
