Who was Radhakrishna-Aai and what was her role in establishing traditions around Sai Baba?

Radhakrishna-Aai was a pivotal devotee described in Chapter 0 as a 'teacher of loving devotion.' Despite having no wealth, she completely surrendered her body and mind to Maharaj and was instrumental in establishing the Shirdi Sansthan by gathering items from other devotees. Her most notable contributions, as mentioned in the text, were the initiation of the night Shej-Aarti and the dawn Kakad-Aarti at the Chavadi. Although she was only in Shirdi for about eight or nine years before her early death at 35, her impact was profound, accomplishing tasks that might have taken another person twenty-five years.
