Concept:The Bhakti movement stressed personal devotion and used regional languages to connect with common people.
Explanation:The common feature of all Bhakti saints was that they composed their verses in the language understood by their followers.
They preached in local or regional languages and travelled from place to place to spread their message of love and devotion.
The Bhakti movement taught that the bond between God and man is based on love and worship, not on performing rituals or ceremonies.
It is not correct to say that all saints rejected the priestly class, because many prominent Bhakti thinkers and early leaders were Brahmins from upper castes.
Women and lower-caste individuals were encouraged to join the movement and express themselves freely.
Many Bhakti saints opposed idol worship and empty rituals rather than encouraging them.
Therefore, the only feature common to all Bhakti saints is the use of the people's own language in their compositions.
