For over 60 years, Giani Amir Singh taught Sikh scriptural texts to hundreds of scholars at his dera in Sattovali Gali, which became a well known school of Sikh learning. In expounding the holy Guru Granth Sahib and other texts such as the Dasam Granth and Sri Gur Pratap Suraj Granth, he had few rivals. Giani Amir Singh, who remained celibate all his life, dressed himself in a white toga. In 1945, he was chosen president of the Ragamala Mandan Committee formed to counteract the movement for the expantion from the Guru Granth Sahib of the last composition, Ragamala, recounting in verse some of the ragas or musical measures employed in the Holy Book. Giani Amir Singh died at Amritsar on 17 October 1954 at the ripe age of 84 and was succeeded by Sant Kirpal Singh as head of the dera.
