One of five siblings: (Sunit, Binita, Sadhona, Nilina and Pradip), Nilina received a  liberal upbringing from their parents Saral Chandra Sen, a barrister and Nirmala (Nellie). She first got interested in music, when her uncle, Panchu took young Nilina to a concert of Angurbala, at a local theatre. Thereafter, she went to listen to Agurbala at her home in Masjid Bari Street. Eventually she trained for nine years under Girija Shankar Chakravarty (1885–1948), noted vocalist and teacher, known for revitalising the khayal tradition in Bengal. In 1934, at the age of 16, she married Ripjit Singh (1906- 1953), third son of Raja Charanjit Singh of princely Kapurthala State. After her marriage she moved to Kapurthala in Punjab and wasn't allowed to sing. Though her husband died in 1953, when she was 32 years of age. Career
After the death of husband in 1953, she moved to Delhi, where she spent the rest of her life. Here she came in touch with Sumitra Charat Ram, an arts patron and wife of Lala Charat Ram of DCM Shriram Group, who then ran Jhankar Committee, a small performing arts organisation in Delhi, which paved way for the establishment of Shriram Bharatiya Kala Kendra in 1952, with Devi as its artistic director. In the following years, she also remained a music producer of All India Radio, Delhi, and producer with state-run Doordarshan TV channel. Meanwhile, after arriving in Delhi, she started her musical training once again, first under Ustad Mushtaq Hussain Khan (d. 1964), the doyen of Rampur-Sahaswan gharana, who was then teacher at the Bhartiya Kala Kendra, and later under Rasoolan Bai of Benaras gharana, where she learned the purab ang style of Thumri, and started performing although under the name, Naina Devi. In her Thumri singing, she stressed on the need to study Nayika Bheda (Ashta Nayika), the eight different kind of heroines classified in the Natya Shastra, to render thumri effectively. Though she also sang in other genres like qawwali and ghazal. Later in life, she got interested in the traditional form of kirtan, she went to Vrindavan and learnt it and subsequently trained three of her senior disciples in the form.
