What were the three specific meditation techniques from the Vedas that Sai Baba recommended to the author for purifying his mind?

Chapter 2 does not outline any specific meditation techniques from the Vedas that Sai Baba recommended to the author. Instead of a prescribed technique, Baba's guidance was more fundamental. He instructed the author to "dissolve his ego and surrender it at my feet," promising full assistance to one who does so. According to Chapter 2, the benefit of listening to Baba's stories is that devotion arises, ignorance is destroyed, and the listener can attain the "entire goal of the Vedas," where self-bliss and knowledge of one's true form are realized. The method is surrender and contemplation of the stories, not a specific Vedic meditation practice.
