God has been the object of search for the best of human minds since the dawn of civilization. These souls have not been the monopoly of any chosen people, but have belonged to the whole humanity. The paths they have trodden and the trails they have blazed, have been many and varied. Several of them have recorded their experiences in their own words while, experiences of others have been narrated by their disciples. Lives of these pioneers in the realm of spirit have been characterized by a high degree of divine qualities, described in detail in Canto XVI of the Bhagavad-Gita. Gandhiji belonged to this race of immortals. Bhagavad-Gita was for Gandhiji a book of reference. He found it of great help and called it his Kamadhenu. It offers an excellent synthesis of the very best that is in Hindu spiritual thought and culture. Questions such as the nature of God, His relationship with the universe and the destiny of the indivual soul have been expounded at length in the Lord’s song aptly called the Song Celestial. Discourses of Gandhiji on the Gita, therefore, find a place of honour in the present collection. To the earnest reader who seeks answers to questions such as, the purpose of human life, how to live and conduct oneself in this world, etc., and guance will be found in the pages of these three volumes. I therefore commend them to his attention and study. I feel sure that he will benefit thereby. “The harvest is plentiful but labourers are few.” The harvest reaped will vary directly with the capacity and effort of each labourer.
