sri guru gita
Guru Gita is a Hindu scripture. Its author is Ved Vyas. In fact, it is a part of Skanda Purana. It has a total of 352 verses.
Guru Gita contains a dialogue between Lord Shiva and Parvati in which Parvati requests Lord Shiva to explain the Guru and his significance. In it, Lord Shankar describes what is Guru, its importance, method of worshiping Guru, benefits of studying Guru Gita, etc.
How glorious is that Satguru who can be? It has been perfectly described in this Gurugita. The ability of the disciple, his dignity, behavior, discipline, etc. have also been shown to be complete. In this way, by going to the Guru's shelter, the disciple attains perfection and he himself becomes Brahmarupa. All his religions, iniquities, sins, and virtues, etc. are eliminated and the only conscious remains left, he becomes multiplied and metamorphosed which is his last speed. Wherever he reaches is his destination. This is his form which he attains.
