At the end of the encounter with Boss Dharamsee, what did Sai Baba say about Kaka's master?

Towards the end of the encounter described in Chapter 35, Madhavrao pointed out to Sai Baba that Boss Dharamsee was Kaka's master. Baba's reaction was sharp and spiritually profound. He replied, 'Where is Kaka's master? His master is someone else.' This statement, which was pleasing to Kaka, served as a powerful teaching. It reframed the concept of 'master' from a worldly, employer-employee relationship to a spiritual one. Baba's response implies that the true Master for any devotee is God or the Guru, not a worldly superior, thereby teaching a lesson on detaching from ego and recognizing a higher authority.
