The primary purpose of this book is to serve as an introductory guide for newcomers to the Ramakrishna Mission. It addresses a common need among first-time visitors who are unfamiliar with the foundational figures of the movement.

The book identifies the "Holy Trinity" as:

• Sri Ramakrishna

• Sri Sarada Devi

• Swami Vivekananda

The book is as a "humble attempt" to provide a concise, "in a nutshell" overview of their lives and teachings, ensuring that even those with no prior background can quickly grasp the essence of their spiritual legacy and the mission's core values.
