SADDĀ SIṄGH, PAṆḌIT, was a Nirmalā scholar, who read Sanskrit with Paṇḍit Chet Siṅgh of Kāshī. He attained such mastery of Sanskrit learning that his teacher made over to him his school before he died. The Paṇḍits of Kāshī honoured him with the highest scholarly rank of Daṇḍīpād, after he had humbled in a Śāstrārtha or debate a man of acknowledged authority in ancient texts.
Saddā Siṅgh translated, in 1767, most famous, but abstruse, Sanskrit work on monism called Advaita-Siddhi into Braj Bhāshā, using the Gurmukhī script.
He gave the translated version the title of Sugamsār Chandrikā. This book, known for its grandeur of style, is an answer to, and a critical evaluation of the various contemporary challenges to the theory of monotheism and non-plurality. It establishes the sovereignty of bhakti. Bhakti, it says, is both a means and an end in itself, where as giān is only a means and is included in bhakti.
Saddā Siṅgh had at his school a succession of pupils whom he trained in Vedic learning. His name is still remembered with reverence among men of learning in Vārāṇasī and his portrait still hangs in Kāshī Saṅgat, the school over which he presided with distinction.
