The book "Strive to Attain God," focusing on the life and legacy of Swami Virajananda who was a direct disciple of Swami Vivekananda, being one of the first four individuals initiated into sannyasa (monkhood) by him upon his return to India in 1897. He played a pivotal role in the Ramakrishna Mission, leading the organization through a period of significant growth, expansion, and public recognition. The book itself is a curated collection of his essential lectures and writings. Much of this material was originally featured in various spiritual journals, most notably Prabuddha Bharata.

In essence, the book establishes the author's spiritual authority and his instrumental role in spreading the teachings of the Ramakrishna Order.
