Prabhuji spoke on verse - 32 of the seventh chapter of Srimad Bhagavatam Canto 11. He spoke on the five different kinds of Gurus and they are - Caitya-Guru, Tat-pradarsaka-Guru, Bhajana-Guru, Siksa-Guru, and Diksa-Guru. And then, he quoted the dialogue between Dattatreya and Maharaja Nimi. Thus, he explained who Dattatreya's 24 Siksa-Gurus were.
