Khorshed Kaikhushru Irani was born on 2 May 1910, the only child of Kaikhushru Masa, a Zoroastrian jeweler of Bombay who was among Meher Baba's earliest followers, and his wife Soonamasi, the younger sister of Gulmai Irani. She first saw Baba on 9 May 1922, at the age of twelve, on a train to Sakori, and from then on she dedicated her life to him. Soon afterwards Baba walked into the family's Bombay home and told her to visit him daily after school at Manzil-e-Meem. She heard Baba speak and sing for more than three years before he began his silence, and late in life she was one of very few who still remembered his voice.
In 1923 Baba introduced her to Mehera, and the two became lifelong best friends. In 1924 Khorshed was with Mehera at Sakori as her companion, and Baba then housed Mehera with Khorshed and her parents in Bombay. When Jamshed's widow, several years older, also joined the women, the two Khorsheds became known as Big Khorshed and Small Khorshed. On her birthday in 1926 Baba wrote that Mehera was Radha and that Khorshed was Radha's best friend Chandrika, and he gave her the nickname Chandula.
From the autumn of 1924 Khorshed lived with the women mandali in their secluded quarters at Meherabad, as one of the first six women to stay there permanently; joined by her mother in 1925, she later lived at Toka, Nasik and on Meherabad Hill. At her father's deathbed in Nasik in January 1931, Baba asked her to sing a ghazal so that Masa's mind would stay on God. In April 1933 she greeted the newly arrived Western women at Kandivli near Bombay with the cry "Baba found!", and in 1937 she travelled with Baba and the women to France.
When the New Life began in 1949, Baba sent Khorshed and her mother to live in Bombay. Khorshed at first withheld the promise he asked for, saying it was of no use now that he was separating her from him; Baba replied that those bound by his instructions can never be separate from him, and she promised. Through the 1950s and 1960s she lived with her mother in their Bombay flat, often called to stay with Baba and the women at Meherazad, Mahabaleshwar or Guruprasad. Her last time with him was at Meherazad in December 1968, when Baba asked her to stay two extra days.
After Baba dropped his body in 1969, Khorshed cared for her mother until Soonamasi died in 1973. In 1981 she moved to Khushru Quarters in Ahmednagar, her cousin Adi K. Irani's family home and now Meher Nazar, the office of the Avatar Meher Baba Trust, where she lived in two small rooms with her adopted family, Sudam and Asha Wagh and their daughters. For nearly two decades she welcomed pilgrims with stories of her life with Baba and taught the children of the compound to sing his arti. She died in her room there on 4 August 1999 at the age of 89, and her ashes were interred at Upper Meherabad beside Meher Baba's Samadhi. Her stories were later published as Fortunate to Love Him (2017).
