What specific instruction did Sai Baba give to Nana Chandorkar regarding the Bhagavad Gita verse 'Upadeksyanti te jnanam...'?

In the detailed account from Chapter 50, after Nana Chandorkar recited and explained a verse from the Gita, Sai Baba directed his attention to the third line, 'Upadeksyanti te jnanam...'. Baba challenged him to contemplate it differently. He pointed out that by mentally inserting an 'a' sound (Avagraha) before the word 'jnanam' (knowledge), it could be read as 'ajnanam' (ignorance), completely reversing the common interpretation. While acknowledging the standard meaning given by famous commentators like Shankarananda and Jnaneshwar, Baba used this 'fun' intellectual exercise to rain 'drops of the nectar of wisdom' upon his devotee.
