Goswami Tulsidas ji
Vinaya Patrika, a humble petition to Lord Rama in the Vraja Dialect, is a devotional poem composed by Goswami Tulsidas ji (1532-1623). It contains hymns addressed in vinaya or extreme humility to different Hindu deities and Lord Rama in particular.
An important composition of medieval Hindi literature and the bhakti movement, the Vinaya Patrika has an interesting story which led to its origin.
Once a murderer came on a pilgrimage to Varanasi and begged: "For the love of Rama, give alms to me, a murderer." Hearing the name of his adorable Rama, Tulsidas called the man to his house and giving him consecrated food,declared that he was purified. The region's orthodox brahmins asked him how the murderer's sin was absolved.
Tulsidas ji responded, "Read your own scriptures and learn about the power of the Divine Name." Not satisfied; the brahmins asked for further proof.
Kashi Vishwanath Temple, Varanasi
All of them said that if the sacred bull of the Kashi Vishwanath Temple would eat from the hands of the murderer, they would accept Tulsidas's words. The man was taken to the temple and the bull did eat from his hands. Tulsidas ji proved that the devotee's sincere repentance was accepted by the Lord.
However a new calamity surfaced as Kali, the embodiment of evil, threatened to devour Tulsidas ji.
Lord Rama & Hanumana
Soon after Goswami Tulsidas prayed to Lord Hanuman who appeared to him in a dream, advising him to file a petition to Sri Rama,the Lord of the Universe, to remedy the evil. And that led to origin of the Vinaya-Patrika.
Kalki Avatara in the Kali Yuga
Vinaya Patrika has been written as a humble petition against the six passions of lust, wrath, greed, inebriation, attachments and ego, and the nine vices of violence, falsehood, pride, envy, strife, suspicion, jealousy, rivalry and covetousness (the defendants) which abound in the Kali Yuga or age of spiritual darkness. Hanuman, the messenger of Lord Rama, is the plaintiff's counsel and Kali Yuga, the age of spiritual darkness, is the counsel of the defendants.
The plaintiff is Tulsidas ji himself, though he represents the whole of mankind. The judges addressed are Lord Rama, Sita, Lakshmana, Bharat and Shatrughan.
