What does Chapter 16 mean when it says the Sadguru is 'Aptakama' and that he dons a 'cloak of ignorance'?

Chapter 16 of the Sai Satcharitra uses these specific phrases to describe the Guru's nature and methods. Stating that the Sadguru is 'Aptakama' means he is one whose desires are already fulfilled; he is complete and lacks nothing. He does not need service or offerings for his own sake. Rather, as Chapter 16 clarifies, he accepts a disciple's service only to fulfill their spiritual yearning and guide them towards becoming desireless. The phrase 'donning the cloak of ignorance' explains his teaching style. The all-knowing Guru pretends to be ignorant to relate to the devotee, imparting profound knowledge and sweet instruction without transgressing social conduct, making spiritual wisdom accessible.
