The provided text, titled "Publisher's Note," explores the profound spiritual foundation of Netaji Subhas Chandra Bose. While most biographies focus on his political life, this booklet highlights how his character was forged by the teachings of Sri Ramakrishna and Swami Vivekananda.

The central theme is that Netaji viewed the struggle for Indian independence not just as a political movement, but as a form of "Sadhana" (spiritual practice) and "Karmayoga." Vivekananda’s philosophy of "Practical Vedanta"—which rejects the distinction between the sacred and the secular—served as the "mighty spiritual current" behind Netaji’s public charisma. Ultimately, the text presents Netaji as a modern embodiment of the Vivekananda spirit, urging today’s youth to adopt a similar character for the nation’s advancement.
