The author of  "Religion and Dharma" was a disciple of who?
Sister Nivedita Bhagini "(Sister)" Nivedita (]    ; born Margaret Elizabeth Noble; 28 October 1867 – 13 October 1911) was a Scots-Irish social worker, author, teacher and a disciple of Swami Vivekananda. She spent her childhood and early days of her youth in Ireland. From her father, and her college professor, she learned many valuable lessons like – service to mankind is the true service to God. She worked as school teacher and later also opened a school. She was committed to marry a Welsh youth who died soon after their engagement. She carried on her life.
Vagbhata Vāgbhata (वाग्भट) is one of the most influential classical writers of ayurveda. Several works are associated with his name as author, principally the Ashtāṅgasaṅgraha (अष्टाङ्गसंग्रह) and the Ashtāngahridayasaṃhitā (अष्टाङ्गहृदयसंहिता). The best current research, however, argues in detail that these two works cannot be the product of a single author. Indeed, the whole question of the relationship of these two works, and their authorship, is very difficult and still far from solution. Both works make frequent reference to the earlier classical works, the Charaka Samhita and the Sushruta Samhita. Vāgbhata is said, in the closing verses of the "Ashtānga sangraha", to have lived in Sind (today in Pakistan), and to have been the son of Simhagupta and pupil of Avalokita. He was a Buddhist, as is shown by his explicit praise for the Buddha by name at the start of the "Ashtāngasangraha", and his praise of the Buddha under the title "Unprecedented Teacher" in the opening verse of the "Ashtānga hridayasamhitā." His work contains syncretic elements.
