Mysticism is Evelyn Underhill's timeless manual, which offers thorough and rich guidance to the principles of mystical Christianity. A classic since its publication in 1911, Mysticism remains an authority on its subject. Despite more modern works providing a more updated or formal analysis of Christian mysticism, none do so with the passion and splendour with which Underhill tackles the subject. Having herself had spiritual experiences, the author mentions that such events inspire those who feel them to action rather than to continual idle reflection of the divine. This publication is derived from treasured 12th edition, renowned for its mindful revisions and additions Underhill appended. In reaction to earlier reviews, additional notes are appended to clarify some of the deeper passages and aid the comprehensive flow of the chapters.

A poet, novelist, and well known writer on mysticism, Evelyn Underhill was born in 1875. She was educated privately and at King's College for Women, London, of which she later became first an Honorary Fellow and then a Fellow. She was also an Honorary Doctor of Divinity of the University of Aberdeen. In 1921 she was Upton Lecturer on the Philosophy of Religion at Manchester College, Oxford. Among Miss Underhill's most notable books are 'The Spiritual Life', 'Practical Mysticism', 'The Mystic Way', and 'Meditations Based on Our Lord's Prayer'.
