The founder of Sri Gopinath Gaudiya Math offers wisdom and clarity about the most vital and least understood aspects of the spiritual path: the teacher. This compilation of articles written by Swami B. P. Puri is a handbook for those seeking guidance in their quest for a genuine guru, for those wanting to learn more about the foundational concepts of the Gaudiya Vaishnava tradition, or for those simply wanting to deepen their spiritual practice. Swami B. P. Puri articulates the qualities and qualifications of both the spiritual teacher and the student disciple. The book describes the proper processes of approaching the spiritual teacher, learning from them, and offering service to them. Guru also explains what students and teachers should avoid in their pursuit of sincere spiritual practice. Firmly rooted in a wealth of ancient Sanskrit and Bengali poetry and accompanied by Swami B. P. Puri's beautiful and elegant translations and commentaries, Guru will be cherished by those with a keen interest in Hindu spirituality.
