The importance of the Bhakti and Sufi saints lies in the new atmosphere created by them, which continued to affect the social, religious and political life of India even in later centuries. Akbar’s liberal ideas were a product of this atmosphere in which he was born and brought up. The preaching of Guru Nanak were passed down from generation to generation. This resulted in the growth of a separate religious group, with its separate language and script Gurmukhi and religious book, Guru Granth Sahib. Under Maharaja Ranjit Singh, the Sikhs grew into a formidable political force in the politics of North India.
The interaction between the Bhakti and Sufi saints had an impact upon Indian society. The Sufi theory of Wahdat-al-Wujud (Unity of Being) was remarkably similar to that in the Hindu Upanishads. Many Sufi poet-saints preferred to use Hindi terms rather than Persian verses to explain concepts. Thus we find Sufi poets such as Malik Muhamniad Jaisi composing works in Hindi. The use of terms such as Krishna, Radha, Gopi, Jamuna, Ganga etc. became so common in such literature that an eminent Sufi, Mir Abdul Wahid wrote a treatise Haqaiq-i-Hïndi to explain their Islamic equivalents. In later years this interaction continued as Akbar and Jahangir followed a liberal religious policy.
The popular verses and songs of the Bhakti saints also served as forerunners of a musical renaissance. New musical compositions were written for the purpose of group singing at kirtans. Even today Mira’s bhajans and Tulsidas’s chaupais are recited at prayer meetings.
