Explanation:

Gurbaani di Kunji Baani Jo Bhai Gurdaas Vakhaani’ namely forty Vaaran and 675 Kabitt-Savaiyye, were written by Bhai Gurdaas ji (1636) at different periods of his life. He was then the honored scribe of Aad Bir, or first recession of Sri Guru Granth Sahib, thus his understanding and knowledge of Gurbaani can be held very close to Guru Sahib’s true intention with the Holy Word. Sikh tradition tells us that even though Guru Arjan Dev ji didn’t include Bhai Gurdaas ji’s writings in Sri Guru Granth Sahib, he awarded his Baani with the title Gurbaani di Kunji or ‘the Key to Guru’s Words.’

The usage of the word ‘kunji’ or ‘key’ means that Bhai Gurdaas Ji’s writings were accepted as reliable explanations of Sikh philosophy as found in Gurbaani. Thus, the word key indicates authenticity. The contents of both ‘Bhai Gurdaas Baani’ and Gurbaani show a similarity, applying that Bhai Sahib based his writings upon the Words uttered by Gurus. The Vaaran have an explanatory function in Sikh circles and are used in the exegesis of Gurbaani. Concepts such as niranjan, oankar, karta-roop, gurmukh, etc are explained in the verses of Bhai Gurdaas Ji.
