Kālidāsa
The most popular theory is that Kalidasa flourished during the reign of Chandragupta II, and therefore lived around 4th-5th century CE. Several Western scholars have supported this theory, since the days of William Jones and A. B. Keith. Many Indian scholars, such as Vasudev Vishnu Mirashi and Ram Gupta, also place Kalidasa in this period. According to this theory, his career might have extended to the reign of Kumaragupta I (r. 414 – 455 CE), and possibly, to that of Skandagupta (r. 455 – 467 CE).
Ramakrishna
Ramakrishna Paramahansa ; 18 February 1836 – 16 August 1886), born Gadadhar Chatterjee or Gadadhar Chattopadhyay, was an Indian Hindu mystic and saint in 19th century Bengal. Ramakrishna experienced spiritual ecstasies from a young age, and was influenced by several religious traditions, including devotion toward the goddess Kali, Tantra ("shakta"), Vaishnava ("bhakti"), and Advaita Vedanta. Reverence and admiration for him among Bengali elites led to the formation of the Ramakrishna Mission by his chief disciple Swami Vivekananda.
