Explanation:

Ramananda

Ramananda was a 14th-century Vaishnava devotional poet saint, who lived in the Gangetic basin of northern India. The Hindu tradition recognizes him as the founder of the Ramanandi Sampradaya, the largest monastic Hindu renunciant community in modern times. 
Nirguna bhakti is devotion to and worship of the Divine as formless. The term comes from the Sanskrit, nir, a prefix meaning “without”; guna, meaning “qualities” or “properties,” and bhakti, which means “devotion” or “faithfulness.”
