It is said in the Introduction to the new Prarthana, a book of songs, verses and prayers by Narottama dasa Thakur that Gaur Kisore dasa Babaji once said the Lord of God could be obtained for five annas. Here is the passage: Srila Goura Kisora Babaji repeated himself, and then told the inquirer to go to the market with five annas (one anna equals a sixteenth of a rupee and in Sep-2004, about 45 rupees equals one US dollar) and purchase two books by Srila Narottama dasa Thakura, Prarthana and Sri Prema-bhakti-candrika. He instructed that by reading and meditating on the contents of these two books daily, one will develop love of God.
