Is Sri Dasam Granth also a Granth like Sri Guru Granth Sahib Ji?

No. Sri Dasam Granth is not one granth like Sri Guru Granth Sahib Ji. It is a kuliyat, or collected works. Sri Dasam Granth is collection of different books in one volume.

Sri Guru Granth Sahib Ji is one granth comprising banee of different Gurus, Bhagats, Bhatts etc. The banee of Sri Guru Granth Sahib Ji is on one theme and subject. It is a spiritual fountain. Primarily it is for the uplifting of the soul and helps it unite with the Ultimate One. The banee of Sri Guru Granth Sahib Ji is referred as ‘Gurbanee’.

Sri Dasam Granth on the other hand is a collection of different books, on different subjects but coming from one pen. The theme of the volumes included in Sri Dasam Granth has a very vast range. Absolute spirituality is found in Jaap Sahib, Akaal Ustat etc. Shastar Naam Mala, Gyaan Parbodh, Chritropakhyan etc form the literary compositions. Then there are Gurmukhi translations of Puranic epics like Ramavtar, Krishnaavtar, Chandi di vaar, Chaubees Avtar etc for the purpose of empowering Sikhs with the knowledge so that they could become aware of the reality of the Hindu scriptures and backgrounds to the characters of the demi-gods and as a consequence able to respond to challenges from Brahmanism. Prior to this only the Brahmans had the monopoly over knowledge. The Guru did not write them as his own composition (Gurbanee) but used his literary skills to translate the Sanskrit works for exposing the Vedic scriptures so that Sikhs forsake the so-called ‘gods’ of Hinduism and realise the reality. The entire compositions are in conformity and aims of Sri Guru Granth Sahib Ji.
