“The Nectar of Devotion is a summary study of Bhakti-rasāmṛta-sindhu, which was written in Sanskrit by Śrīla Rūpa Gosvāmī Prabhupāda. He was the chief of the six Gosvāmīs who were the direct disciples of Lord Caitanya Mahāprabhu. When he first met Lord Caitanya, Śrīla Rūpa Gosvāmī Prabhupāda was engaged as a minister in the Mohammedan government of Bengal. He and his brother Sanātana were then named Sākara Mallik and Dabir Khās respectively, and they held responsible posts as ministers of Nawab Hussain Shah. At that time, five hundred years ago, the Hindu society was very rigid, and if a member of the brāhmaṇa caste accepted the service of a Mohammedan ruler he was at once rejected from brāhmaṇa society. That was the position of the two brothers, Dabir Khās and Sākara Mallik. They belonged to the highly situated sārasvata-brāhmaṇa community, but they were ostracized due to their acceptance of ministerial posts in the government of Hussain Shah. It is the grace of Lord Caitanya that He accepted these two exalted personalities as His disciples and raised them to the position of gosvāmīs, the highest position of brahminical culture. Similarly, Lord Caitanya accepted Haridāsa Thākur as His disciple although he happened to be born of a Mohammedan family, and Lord Caitanya later on made him the ācārya of the chanting of the holy name of the Lord: Hare Kṛṣṇa, Hare Kṛṣṇa, Kṛṣṇa Kṛṣṇa, Hare Hare/ Hare Rāma, Hare Rāma, Rāma Rāma, Hare Hare.” – Taken from the preface to The Nectar Of Devotion by Srila Prabhupada
