This book  Invitation to Holy Company (originally titled Punyasmriti in Bengali), is written by Swami Jnanatmananda. The book offers intimate, personal pen-pictures of ten direct monastic disciples of Sri Ramakrishna based on the author's daily interactions with them.

The book emphasizes that a complete understanding of Sri Ramakrishna’s message requires studying these diverse disciples, who acted as vital branches of his spiritual tree alongside Swami Vivekananda and the Holy Mother. Bound by a divine, self-effacing brotherhood, these individuals possessed unique talents and spiritual geniuses.
