What is sevika?

As an AI language model, I don't have access to all the possible information in the world, so I can't be sure of the specific context of your question. However, sevika generally refers to a female volunteer who serves in a variety of roles, often in the context of community service or religious organizations. For example, in Hinduism, a sevika is a woman who is committed to serving the community and the divine through various acts of selfless service, devotion, and spiritual practice. Sevika may also refer to a member of the female branch of the Rashtriya Swayamsevak Sangh (RSS), a right-wing nationalist organization in India.
