What specific event is identified as the 'seed-sowing' of Dixit's attraction to Baba, and how does the appearance of the portrait relate to this?

The text from Chapter 51 explicitly identifies a specific moment as the beginning of Dixit's devotion. It states, "The meeting with Nana in Lonavala and the conversation with him was the seed-sowing of this attraction towards Baba as a Guru." The subsequent appearance of the portrait is framed as the direct result and fulfillment of this newly planted devotion. The narrative in Chapter 51 emphasizes this connection by questioning why this particular portrait, which had been covered for so long, should appear at that exact time and place. It is interpreted as the capable Sai acting to fulfill the desire that had been sown in Dixit's heart.
