Amjad Ali Khan was giving a concert of Indian classical music at the Commonwealth Institute, London, in 1981. He was a sarod player of some repute and being a public performance, the concert had started at the allotted time, but Shri Mataji had not arrived. His playing was superb, and during his performance Shri Mataji entered with Her husband. Amjad respectfully acknowledged Her arrival by rising slightly and bowing to Her.
After that, his performance went through the roof and took you to another level altogether. It was a spiritual experience. Afterwards he apparently acknowledged the difference in his performance after She had arrived.
