Solution:

Sree Narayana Guru was born into a family of the Ezhava caste in an era when people from such communities, which were regarded as Avarna, faced much injustice in the caste-ridden society of Kerala. He led a reform movement in Kerala, rejected casteism, and promoted new values of spiritual freedom and social equality.[1] He stressed the need for the spiritual and social uplift of the downtrodden by their own efforts through the establishment of temples and educational institutions. In the process, he denounced the superstitions that clouded the fundamental Hindu cultural convention of caste.
