An important aspect of the Râmat movement is its effect on the popular literature of Hindustan which in the fifteenth and even more in the sixteenth century blossoms into flowers of religious poetry. Many of these writings possess real merit and are still a moral and spiritual force. European scholars are only beginning to pay sufficient attention to this mighty flood of hymns which gushed forth in nearly all the vernaculars of India[608] and appealed directly to the people. The phenomenon was not really new. The psalms of the Buddhists and even the hymns of the Rig Veda were vernacular literature in their day, and in the south the songs of the Devaram and Nâlâyiram are of some antiquity. But in the north, though some Prâkrit literature has been preserved, Sanskrit was long considered the only proper language for religion. We can hardly doubt that vernacular hymns existed, but they did not receive the imprimatur of any teacher, and have not survived. But about 1400 all this changes. Though Râmânand was not much of a writer he gave his authority to the use of the vernacular: he did not, like Râmânuja, either employ or enjoin Sanskrit and the meagre details which we have of his circle lead us to imagine him surrounded by men of homely speech.
One current in this sea of poetry was Krishnaite and as such not directly connected with Râmânand. Vidyâpati[609] sang of the loves of Krishna and Râdhâ in the Maithili dialect and also in a form of Bengali. In the early fifteenth century (c. 1420) we have the poetess Mirâ Bai, wife of the Raja of Chitore who gained celebrity and domestic unhappiness by her passionate devotion to the form of Krishna known as Ranchor. According to one legend the image came to life in answer to her fervent prayers, and throwing his arms round her allowed her to meet a rapturous death in his embrace. This is precisely the sentiment which we find later in the teaching of Vallabhâcârya and Caitanya. The hymns of the Bengali poets have been collected in the _Padakalpataru_, one of the chief sacred books of the Bengali Vaishnavas. From Vallabhâcârya spring the group of poets who adorned Braj or the Muttra district. Pre-eminent among them is the blind Sur Das who flourished about 1550 and wrote such sweet lyrics that Krishna himself came down and acted as his amanuensis. A somewhat later member of the same group is Nâbhâ Das, the author of the Bhakta Mâlâ or Legends of the Saints, which is still one of the most popular religious works of northern India.[610] Almost contemporary with Sur Das was the great Tulsi Das and Grierson[611] enumerated thirteen subsequent writers who composed Râmâyanas in some dialect of Hindi. A little later came the Mahratta poet Tukarâm (born about 1600) who gave utterance to Krishnaism in another language.
