A brown study is a reverie: musing, pondering or meditating, with a touch of sadness. Heathenland is the author’s name for the ancient land of which India is the heart, defined in the opening paragraphs of Topic 1. The title names the book exactly: a long, searching meditation on that land and its people.
The book is in four parts. Part I sketches the land and takes up the first questions: life, soul, God, prayer, fate and sin, then justice, law, religion and government. Part II turns to salvation, spirit and death, and to the long history of worship, priesthood and caste. Part III is the thousand years of invasion and the road to Partition. Part IV looks at India now and ends with the Bhagavad Gita and the practice of yoga.
Sixteen plates illustrate it, all but five drawn by the author: maps of Heathenland across a million years, and cosmic diagrams of the universe as he understands it. They are gathered in the Atlas.
