This book opens the way to a deeper knowledge of mahamudra, a Buddhist system of meditation on the nature of the mind. In providing a detailed commentary on the Vajra Song of the first Jamgön Kongtrül (1813-1899), the author elucidates the stages of ground, path, and fruition for those who wish to meditate according to this system.

Jamgön Kongtrül (1813–1899) was a versatile and prolific scholar. He has been characterized as a "Tibetan Leonardo" because of his significant contributions to religion, education, medicine, and politics.
