Extracts from the Baha'i Writings on becoming spiritually strong. Introduction and notes by Geoffrey Gore.

This book explores the concept of becoming spiritually strong- a condition referred to in the Baha'i Holy Writings as 'firmness in the Covenant'. Beginning with the heart and then looking at the importance of vision and understanding, the process of becoming spiritually strong is treated as an exciting journey of discovery, leading to a condition of spiritual happiness and true liberty. To reach that condition is to fulfill the spiritual destiny of the soul, and attain what Baha'u'llah describes as "... the City of Certitude".
