Perhaps it is well for me to explain that the subject-matter of the papers published in this book has not been philosophically treated, nor has it been approached from the scholar's point of view. The writer has been brought up in a family where texts of the Upanishads are used in daily worship; and he has had before him the example of his father, who lived his long life in the closest communion with God, while not neglecting his duties to the world, or allowing his keen interest in all human affairs to suffer any abatement.
